MTN Worst service provider

Someone at MTN decided to upgrade my contract in March 2024. I did an affidavit in March 2024 and till this day I have never gotten feedback. I have never not paid my account with MTN but my calls have been blocked. I cant receive calls or SMSs. When I call to enquire I get people who give me attitude and no one is able to help me. I have been using MTN for almost 20 years now and this is the worst service Ive ever received. You guys should be ashamed of this, I am inconvenienced and no one in your company seems to care. Your ***** department is the worst’s. Nothing bores me more than the fact that I have to constantly call and no one seems to be able to help. Im going on my 3rd 21 days wait but not a single person has bothered to get back to me or solve my issue
