My worst nightmare with MTN

I am up for an upgrade on my account next month on 17September2024. I called MTN to schedule a cancellation on 17August 2024 and I was told that I have a soft suspension on my account so the request is not possible. I spoke to seven customer care agents all telling me different things. Eg. Payment of a cancellation fee, arrears on my account, ect However, finally I was advised the suspension will be lifted within 24hrs to 72hrs, and the cancellation will be scheduled. I was given a ref number. I called today to find out if wether the suspension has been lifted. To my demise, the suspension is still there on the system. The gentleman I spoke to managed to convince me not to cancel but rather upgrade to a lesser package inorder not to tarnish my standing with MTN, as I have a 'positive' track record with MTN. Fine, I resorted to the lesser package. Only for him to advise me to call transunion because of my credit rating. It's not my fault that the soft suspension was never lifted on the system as my account is up to date. I don't want anything to do with an MTN contract anymore please, I just want to part ways. I gave my notice 30days prior to an upgrade for a cancellation and its not my fault that there was a soft suspension on the system in the first place.I am exhausted. Please help!!!
