MTN Canellation of contract

I had an unbelieveble battle with MTN on the cancellation of a contract. Don't think you can inform CUSTOMER SERVICE of a cancellation, they are useless. I recieved increasing invoices for approx 6 months, alhough I went trough the steps and even got a refrence number for the cancellation send to me by Lindiwe Maseko Ref No *** dated 2021/03/10. Every following month I recieved an account from MTN informing me of an accumulating account for 6 months. Then a lady : 'Jasmin Mamoojee' phoned me about the matter. After some "heated discussion" she assured me that she will assist in resolving the problem. - and teally TODAY 24 June 2021, I recieved an invoice from MTN that I owe then R0.00. I am not sure how to express my appreciation towards Jasmine, because the service and attention I recieved of MTN CUSUMER CARE would end up reflecting on my credit rating as negative simply due to the fact that CUSTOMER CARE did not read my monthly return mails and was FAST ASLEEP. MTN CUSTOMERS BE AWARE, BE REALLY AWARE, THAT MTN CUSTOMER CARE DOES NOT CARE ABOUT CUSTOMERS!!!! Jasmine, I thank you and I trust MTN VALUE your VALUE.
