MTN incompetence

MTN doesn't even deserve even a star on this, I'm writing this email with great concern, I'm not getting any joy from MTN, and the service sucks big time, one is left frustrated, angry and annoyed with MTN call center agents who don't know what they are doing, today I received SMS telling me I have been upgraded, when I call customer service to check what I have been upgraded to, none of the agents are able to assist, what they are good at is to give me *** number to call and choose option 2, when I'm doing that, MTN agent will tell me to dial 135 as they can't help me, today I have spoken to about plus 10 agents and none of them managed to help me, I spoke to Zanele, Ziphokazi, Mbali, Princess just to name few. I even tried asking to speak to any of the managers available and I was told non of the managers are working on the call centers, what I want is simple, cancel the upgraded contract that was done on the 20 July 2020, I'm no longer interested in MTN offerings as you guys are *********** in your work, you are only good in transferring my calls to the same number *** saying you don't deal with that I deal with this, where is customer service in that? I even visited MTN wonder park to seek for help, I was told to call 135 and choose option 3 and 0 and that I did where I was told to dial *** again and again. The contract number in question is ***. please cancel the upgraded contract *** and soon as *** expires as well I'll cancel it as well, I'm done with MTN incompetence.
