Picture freezing

For several weeks now, my picture has been regularly freezing up no matter what channel I'm on.

At first, the freeze would last for 15-20 seconds, and then the show would resume.

Now, it's starting to freeze and will stay that way for hours. When that happens, my remote control

is not usable at all.

The only way to resolve the situation at that point, is to unplug the cable box.

Doing that fixes the problem, but since I have to do that every day or so, my guide is constantly 

erased, so I never know what's on TV. Everything is "To Be Announced" until, in a day or so, the 

picture freezes again and the whole process starts again.

When I call customer service, all that happens is the phone employee gets extraordinarily excited, 

shouting that this is very, very good news for me! 

Because I can get internet service for just (insert some amount of money I'm not interested in giving

a company that already isn't delivering one service reliably).

If we can get my TV working reliably, I'm more than willing to have a conversation about additional

services, but I will not invest $0.01 more in a company that isn't delivering what I'm paying for already

and demonstrates little interest in fixing that.

Please help me get in touch with an employee who can help to fix this issue.

Thank you.
