Coin.mx not very user friendly

In my frustration with buying bitcoins I started trying different sites and exchanges I've never used before. I came across coin.mx and it seemed pretty legit. Had testimonials with the peoples facebook page links, had live chat support and a seemingly simple verification process. I signed up, put my card information in to verify it would work, it said it was accepted and then I put my card information in to do deposit of 55$ because on the site they were advertising that if you deposit 55$ that you will get 5$ free. As soon as I put through the deposit I got an email from my bank saying 72.50$ was taking from my account not 55$. I went back to coin.mx and it showed a message saying I needed to verify my identity with a video of my self holding my I.D, credit card and show both sides. So that made me a bit nervous but I did it, sent it but then I recieved a message that it wasn't accepted because I didn't show the back of the card for long enough. That made me more nervous because the security number is there. A live support chat person popped up and to "assist" me but I told them I want to canel the transaction. After telling them that they persistantly tried to convince me over and over again to try and verify after telling me 3 or 4 times that I wanted to cancel the transaction. After an hour of going through that with the support person they eventually said the transaction was canceled and I should receieve the money back in 3 buisness days, that was on Saturday it is now Wednesday, the money has been added back to my saccount but over all sketchy expeariance.
