Let me tell you all something. I have worked with every domain registar out there. I have never seen a more unethical, borderline criminal company than Register.com.
So much so, I am literally taking a hit of transferring every domain from every client who uses them. Here is a short story.
I had a client who had one of their friends built a website. This wasn't under our scope of work umbrella. Website was hacked. I was brought in to fix it. They use register.com. I contacted support to help investigate. Dead End. I initiated a backup restore for both database and webdir, both failed. I asked support why they failed. Told me to call back Monday (This was Friday afternoon). Called back yesterday. I was told even though we paid for a backup service, we need to pay them extra to recover the backup. I was like nope. Then the technician hung up on me when I asked to speak to a manager.
I got on the phone again, told them my experience. They said my client didn't have backups. I screenshotted the 5 months of backups for them. They said I had the wrong account. I told them, they had the wrong account. I need help with this specific domain. Clear as day.
That rep put me on an endless hold.
Then I contacted client. Told this person it's in the companies best interest to transfer out all 4 of his domains to another registrar. He agreed.
I get on the phone again. Because even as the admin on the account, I couldn't manually unlock the domains for transfer. Insane. I talked to someone who told me that department went home for the day. This was 4pm pst. I then went to the website chat. This person said they could help. Except, even though I gave them the security pin, they wanted me to give them another pin from my accounts email and phone. Except, when they sent it, and I gave it to them, they kept saying it was wrong. I literally screenshotted each email, and the person kept saying it was incorrect.
Finally, I told them to try another way. B/c I am literally in the admin panel, and ALL I need is to unlock these domains for transfer. Then all of a sudden a new person appeared in chat trying to make deals with me to stay. I was like no. I need these domains unlocked immediately. My client's business is losing money everyday register.com stalls.
Finally after 3 days and 8 hours on Monday of being transferred and told they couldn't help me, the domain lock was removed.
But wait, there's more!
I got to start the transfers to Godaddy. And got to get the authentication code (Just like any other registrar) it is telling me I need to CALL and speak to a representative to get the authorization code. I was like WTF. I call again, they kept trying to make us stay with deals. I was like no. Approve the authorization. The person on the phone said, ok, let me approve them. I get an email, one for every domain saying that I will receivedthe auth code in 1-3 days if approved.
Guys, I have never in my life seen such bad businesses practices. Avoid this company like the plague. I move domains all the time depending on site functionality, but this was pure bad business practices. The bad part about this, is the client is without a website for at least a week or more, and we haven't even got the auth codes to start the transfers.

And to top it off, they decided to spam me for transferring domains with 67 emails to setup an email with them.

Register.com used to be amazing back in the day in the 90s. It was a mainstay. It was bought and ever since then *2005ish it is horrible. I am now pulling the plug on all services with them.

I had professional e-mail with them which I thought was great - $40 ish per year for any domain mailbox like a custom e-mail. With it I use desktop e-mail (i-mail) as I have many e-mails. The coll thing with register was that you could get e-mail even if your domain (which you must own( was registered with a different company - in my case squarespace. Here is the catch. They moved data to new servers and many people's mailboxes have disappeared and stopped working with no explanation. IN the online interface the mailbox is also gone, But you can; t re create it because it says there already is one, On june 2 all my e-mail with them stopped working, The worst part - after spending 10 hours with multiple customer service techs over 2 weeks, noone can fix it. Even worse - their support is unorganized and functions only on one basic level with no upscaling or expertise capability whatsoever.
- no tracking of tickets
- no notes even when they say they are putting down notes for the next tech
- no escalation of skilled techs.
- each tech starts from scratch and each one says somethign different!

I have not read my e-mail for one month,
They have offered me no refund for this month and no solutions.

In fact everytime i call (after being on hold for 30 minutes) I have to start from scratch. Once a tech said they needed to study the situation and i was holding for one hour - I was not able to talk with him - but I had to go. Today I spoke to someone who said they promised to figure it out and then put it in the notes. Teh next tech said tehre were no notes. I am at my whits end with important notices i have missed (grant I applied for etc that I am supposed ot hear form lost e-mails :(. I have used them for 10 years plus and another problem I had also was that they started adding random charges, like $18 every month for an SSl certificate. Then then also aggressively try to get your to renew services and send alarming messages to you with no detail. I own several domains and a few I wanted to retire so I set them to not renew. The messages though do not contain detail - they just say - service expiring and set for deletion tomorrow - click on this link. It's a real pain. Half the site is managed by AI text messages also. Use fatcow or - yeiks - google if you can - not these guys. I use squarespace for website and now am going with google workspace when they can set it up,

Later: I just called google tech support to get them to set up this mailbox and the text after I held only for 5 minutes. He said he was sending me an escalation form so that an advanced programmer can look at why they are also coming up with this error. It was like night and day (not that I am a google fan in fact I avoid it). In the end - use google if you need custom e-mail - DO NOT USE REGISTER.com - worst customer service ever (nice but NO SKILLS), I would compare it to verizon high speed internet in NYC in the 90's. I am lodging a BBB complaint against them.
