MTN ******* service and *********** staff.

MTN is totally ***********.end of 2021 I cancelled my contract with them as they decided to increase my debit order amount even though I had 6 months remaining in my contract.I got a quote to cancel my contract and I made the payment to cancel my contract.over a week and a half later MTN then decides to debit my account of Over R5000 for the cancellation amount so at this point MTN had over R9000 of my money.I phoned my bank and reversed the amount they debited. After going back and forward with MTN they finally sorted the issue out and said I no longer owe them anything. However January 2021 came and MTN had flagged my name with the credit bureau for a missed payment because I reversed the debit amount they tried to take. again after going back and forward and sending them proof of the issue they said they will send a note to the credit bureau to remove this off my name. We are now in July and the mark is still on my name and I am having issues trying to get a home loan because of this. I have been struggling for 4 days straight now trying to get MTN to sort this out. I get told they will get back to me in the course of the day but nothing. I’ve sent emails to the legal department and again nothing.sent in complains and nothing. I have even phoned in and was advised they will send me an email and I must provide them with the emails I have confirming the issue and it’s now a day later and no email has been received. MTN is so *********** that they even affecting my personal life even after I canceled my contract, I guess the next step is to port my number.
