Welcome to the forums
I'm sorry to hear that you're experiencing freezing on the TV service. I'll be happy to help check this out for you.
I have connected to your boxes remotely and there are signal issues that need fixing. To do this I will arrange for an engineer to call out for you.
I'll pop all the details in a private message. (Look for the envelope icon above)
