Worst service I have ever had

Bt vision is quite possibly the worst product I have ever purchased. Has not worked tidy from day 1. Always freezing, switching itself off, even films I have paid for freezing. Now it is so bad I cannot watch a singal programme without it freezing. Also the bt customer service is the worst I have ever had to deal with. I thought Sky was bad but I am going back to them, the lesser of 2 evils I guess. I would advise anyone thinking of switching to Bt vision to stay with sky or freeview as it is a complete waste of money.
