Its a crime to pay off a contract at MTN.

I have been on contract for more than 12 years, the problem only started after I asked to pay off my laptop, I paid the early termination fee on the 27th of January 2021 and on the 1st of February the debit order still went off I called 135. I was told after making a payment I was supposed to call in for retention to cancel my contract. I did just that only to be told my main number will be reverted back to prepaid but I will still be paying for it. I was advised to call activation department so that they can swap the sim cards they referred me to billing, of which billing referred me back to retention. I have been on hold for the past 1hour only for the consultant to put me on hold claiming they cant hear me my line is breaking while my network is on full bar on my side he's going to reboot, only for him to put me back on the queue to hold again only God knows how long will I hold on again. Its almost 2weeks of trying to sort out one small issue that no one has an idea how to resolve it. I hold for 3hours every day to sort out this issue but no solution to the problem. All your consults (Thelma Ngobeni,Shareen, Nokukhanya Motiang, Kutlwano Makaba, Zinizi, Sybel Dlamini and many others that answered my call I think your system can show you all of your *********** consultants I spoke to) don't know how to do their job, they promise to call you back they never do. It is not my fault that your consultants your consultants messed up my lines. Can this be rectified with immediate effect. Your service is appalling .
