Welcome to the Community, I'm sorry to learn about the problems you're experiencing with your TV service recently. I've been able to locate your account and run some tests on the set top box from our end for you.
We're seeing some issues with the set top box from our end and I'd like to arrange for an engineer to come and take a closer look if you're available? I've sent you information regarding this in a private message, which you can view by clicking the purple envelope on the top right of this page.
Apologies again for the inconvenience caused, we're looking forward to getting this sorted.
