Mweb just doing their own thing and ignoring me

Hi, im super annoyed. I keep trying to phone and then my call just goes on silent/dropped call. Ive reached the limit of queries i can log on the app and the newer ones just get ignored. I need to change ownership of my account as new people are taking over my flat and thus my internet. They should be billed for month of May as they will be living in the flat and not me. I phoned to hear what my options were in case of not a full months notice about 2 weeks back and the mweb person gave me the two available options. I told the mweb person ill get back to them with a answer. Next thing i know i recieved a email saying i cancelled my account. Which i never said im doing. Please can someone from mweb give me a call so the banking details can be changed to the new peoples details. Line does not need to be cancelled. If i keep getting ignored im going to stop my debit order at my bank. And if you bill me im going to keep on disputing it. Really annoyed by your ****py costumer service.
