Everything worked fine until it got my credit card number. Then it displayed the message INTERNAL ERROR 500. It was totally locked. I called the phone number they had for help and got 20 min of a recurred msg trying to sell me cable TV, insurance and other stuff. I finally got a computerized voice which could not understand the problem. It also couldn't connect me to a real person and hung up on me. My credit card had been charged, and I can't get it refunded.
