Bad service from the MTN retention team

MTN does not want cancel my contract. I spoke to Siyanda Khete from the retention department who said I fail verification because I said that my bank account type is a current account instead of a cheque account. Which is literally the same type of account. He said I must go to an MTN branch to get my profile unlocked. They need to educate their staff. It’s ridiculous that the people who they trust to do verification do not know that the Cheque account and Current account are the same thing. The worst part is I was verified by the cancellation department and sent to the retention department and they started the process again and told me that I have failed verification. I don’t think they would’ve done that if I was taking up a contract. I’m really disappointed with their service and I plan to cancel all my contracts with them. Now I remember why I ported my cell number to Vodacom. Extremely bad service from them.
