Pathetic service from Mweb !!

Pathetic service from Mweb! Got Mweb fibre about 3 months ago, since then technical problems and zero service, recently a week without wifi, many calls to call centre, incredible queues/waiting times to follow up on technical problem and then when fed up to to ask to cancel contract, zero response, also number of emails to cancel contract (to ***, the correct address according to Accounts), but zero response. Call centre told me they will send documentation for cancellation and cancellation fee, to pay before 15 Jan 2024, then next debit order wont go off, they of course did not send anything. See there are lots of complaints on Internet about their service and how they don’t respond to cancellations. Service is measured when there is a problem, 0/10 for Mweb. I already got another contract, just want to get rid of Mweb!!!
