I signed up for a 6 month trial. I cancelled before the 6 months finished, as they were over spamming my customers and I was getting a bad response from everyone they were targeting.
After canceling, I thought it was over. NOPE. Signpost continued to bill me, beyond the 6 month trial. I only noticed at the end of the year, so they charged me for 4 months, without providing service. I know this, because for the first 5 months, I would get 20+ emails from signpost daily. These stopped when I cancelled the service, but they kept billing me. I had to cancel my credit card to prevent them from getting more of my money.
After Posting this review, I did receive a call from a very helpful customer service rep from signpost.
She was able to work with me to get 3 out of 4 months of service refunded, which is why I have changed this from one star to 3 stars. If the customer service rep I spoke to was running the sales dept, signpost would be much better off.
I cant say I would recommend Signpost, but I can at least withdraw my assertion that they are a fraud/ scam.
