Sometimes it's the customers fault
I have a phone line and fibre package with Virgin. Over 3 years it went up to 49/month
I phoned them last week to ask to get rid of the phone part of the package. I was told that I was on a "package" that no longer existed and that I could keep everything I had for 32/month as that was an equivalent deal if I was a new customer.
They had tried to phone me several times and I'd always ignored their calls, assuming they wanted to sell me something extra.
The guy on the phone did me a favour but also made out it was my fault for not listening to them about offers they had. Seems to me they make their prices up on the spot. But hey ho, that's quite a saving so happy days.
