Get yourself a new provider then mate. I've got EE broadband £19pcm pefect for streaming football and I get an extra 5GB on my phone in the bundle.
Includes line rental. You have to pay for your calls, but does anybody actually use a home phone to make calls anymore ?
My old internet provider contract was up anyway, but EE offered to pay any exit charge if your ISP charges you for leaving the contract early.
I pay £19 a month for my Internet and then me and my brother in law go halves on a Now TV package with Sky sports. 4 devices so two each and £17 each which isn't bad.
Other option is ring up to cancel and when the cancellation team phone you back get loads of knocked off n some free BT sport or something. Easily done if you're good at that sort of thing.
Even my old dear managed to get loads knocked off her monthly bill by threatening to leave. And she's your classic older generation tech wary never switch type of person.
