Welcome to the Community, I'm very sorry for the problems you're experiencing with your set top box at the moment.
I've located your account to take a closer look and can see you've had an engineer out to take a look at this recently, I hope that means that things are working as they should?
If not, let me know and I'll arrange for this to be escalated so we can get this resolved.
I'm sorry again for the inconvenience this has caused.
