Random Add-ons on bill

After grumbling for ages about horrendous price increases for my TV and broadband package I looked at my bill in detail and found that apparently I'm paying extra for TNT Sports and a Kids package. Neither of which I've ever requested or have any use for. This must have been for at least a year - yes I should have looked more closely much sooner! They were certainly not payable extras I'd originally had on my contract.

Trying to get through to the right option when calling 150 on the phone proved impossible. Web chat didn't go anywhere either.

Has anyone else had experiences with these random Add-ons, and how to get those resolved?

I'd quite like the money for them back and really don't want it to trigger another 2 year contract if I ask for it to be removed...
