Authorize.net has HORRIBLE customer service! I signed up on July, and cancelled my account with them right the next day. They told me everything was fine, and that the cancellation was approved and nothing will be charged. A month after (August) I see a $99 set up fee charge on my debit card. When I called to have them return my money, they said I needed to contact my account manager "Mike" so he can refund me that money back to my account. I called him for weeks and weeks, left many many messages/voice mails, and he NEVER called me back nor emailed me. Every time I called no one was helpful, until finally a month and 10 days after (September), a manager picks up the phone and transfers me to Mike, and supposedly that money will be back in my account, but I have to wait 10 business days to get it back. So I have had to deal with this headache for two months now, and still no money back. DO NOT USE THEM! HORRIBLE HORRIBLE SERVICE!
