No internet service for more than a month and still billed and expected to pay

I recently moved to a new area and decided to do a change of ownership from the previous tenant to my details. Change of is firstly delayed and only done almost two months later because I asked for it to be cancelled. The internet has not been working since 1st Sept to date but yet I am expected to pay this invoice. A few reference numbers: #40290, #39598 to log a fault and yet they cancel the request and nothing happens. Now they want to charge me a cancellation fee for something I have not used since I moved into my new place.
