Eventually got through to a Human Being on the phone (after a wait of some 16 minutes, having previously been informed that the wait would only be 3 minutes!), and explained the situation.
I was told this was a known fault, and it was corrected remotely within 3 minutes by the Human Being.
Can I ask why this "known fault" is not advertised on the website, with a direct number to a Human Being so that it may be corrected quickly, without having to wait on the phone listening to excrutiating music for 16 minutes? PLEASE!
I sincerely apologise for the problems you've experienced with losing channels 108-120. There's obviously a lot of content missing when these channels go down.
I've managed to locate your account to check this out. The system was reporting a local SNR (signal to noise ratio) fault in the area. These aren't put on our service status page because they usually don't affect that many customers.
When the call was passed to an agent it was found out the SNR fault was not the cause of your problem. All they did to resolve the fault was send signals to update the box.
All TV faults go through the same line I'm afraid whether big or small. I apologise once again for the inconvenience caused on this occasion and hope that's the end of the problem. Please let me know if you have any further issues.
