MTN responds here to fool the masses, as if you will be helped but nothing happens

This is my 2nd complaint on this issue as I was told in a blanket response, someone would call me in "48 hours". Mtn (retentions) sold a month- to - month 8 GB contract to me in April as I was cancelling my expired contract. It seems it was a trap and I am not getting assistance to cancel it since last week Tuesday. The same consultant who sold this to me decided to capture it as a 24 months contract. I have escalated to a team leader (supposedly) whose name is Nwabisa, she has been avoiding my calls ("in meetings or has a lot of escalations to deal with") and will call me back, all I'm left with is a refence number. What is so difficult with getting my call recording and cancelling this contract? Perhaps delaying tactics for one or 2 more debit orders? This is very cheap and low for a "Bozza network" as they claim when answering the calls. These ****** responded as if someone is going to help me, I'm still waiting until today. It's been a week now, they're clearly doing nothing about this but will expect me to continue paying?
