MTN sucks!!!!!

I have written a review on MTN months ago and my problem/complaint still persists. I have been calling this company since May regarding my contract cancelation processes and the problem still persist after they had promised to get the matter sorted. My line has even been suspended numerous times and worst of all none of their so called service champions could explain my billing. The matter has been going since May 2019.I am really annoyed and frustrated by this,i regret the day I took a contract with MTN.
