NO RESPONSE FROM MTN

I settled my MTN account a month ago and sent proof of payment to [Email Removed] I called him to confirm if he has received and requested to cancel my contract. Do a sim swap and change my card to prepaid. He said that all is done from his side I must call the callcentre request for my contract to be changed then do a sim swap. System has not been updated my account is still with the legal department. I have been without a phone for almost 6 months now trying to sort out these MTN issues. This is the third time I am writing this complaint on helo peter. It is totally unacceptable. My contract was settled early I unfortunately forgot to end the contact till it ended up in areas. It took me 4 months to get feedback from the legal department interms of how mush I was owing now I have settled my account its going to take them another two months to update the system so that I can start receiving my calls. No one even bothered to notify me that my account was in areas I only found out when I had lost my phone. All I want is to close my contract and change my card to prepaid then only I can do a sim swap and start receiving calls.
