Like others have posted they are an outright scam. I signed up for a free trial only to find it lacks half the features of a real account, so I could not assess if it was useful or not. I tried to cancel through the portal only to find they don't allow this. I emailed support 5 days before I was due to be charged and requested they cancel it. Charles pretended to not be able to find my account even though I showed him screenshots as proof of my account email and credit card. He delayed it some more until I was charged. I asked for a refund and now he is trying to tell me that once they make a charge they don't give refunds. Not sure what you think, but this is blatant theft and bad business practices. Now I'm doing a chargeback through the bank to get the money back.
The thing is if they actually had a good product I wouldn't have cancelled my account. If they actually had a good product would they have to act like such douchebags? No.
