Do not choose MTN as a service provider

MTN has suspended my account last week and I dont know why. The first thing I did was to try and call 135 so that I can understand why my account is suspended, I mean if it is in arrears I would like to make payment arrangements which is unlikely because I arranged for a debit order. So I tried the 135 number like a million times and its no help at all, Tried the app and that thing is even more useless. I logged online complaints, sent numerous emails and even social media and no response from MTN. "Everywhere you go", so where the hell are you now. I never received any invoice or billing info from MTN and they just suspend my account without any explanation. Its funny when you want to open an account or get a contract from them, they respond instantly but when you have a complaint or need help they ignore you. I regret choosing MTN, so disgusted by them and the poor service.
