I had a 10$ credit on the site, so I put that into my purchase of a 15$ certificate. When I was checking out the site said 5$ would come off my debit card and 10$ would be applied from my credits, so I checked out. I used the certificate and then a few days later the company charged me the whole 15$. They told me they could not refund the 10$ even though I clearly had the credits on the site, and explained to me how it is my fault, that I must have used the credits wrong. Considering there is a button that you press that says to add all of your credits, to the purchase I am baffled that they think I could have gotten this process wrong. Keep your site credits, I will never use this company again.
