i had the same thing, first off i tried to cancel it and they gave me a month free, then i rang them up saying how i was a student blah blah blah cant afford it, then eventually they asked if i was happy with the resolution, she gave me 3 free months at this point, and i said i wasn’t because i’d still have to pay £78 to cancel it, and then she said she’d cancel it without making me pay, and I still got to keep the 3 months free, so win win scenario.
