MTN CALL CENTRE CLUELESS AND UNPROFESSIONAL

My contract is due to end in a month's time. I called the call centre to inform that I wish to terminate the contract as the 24 month subscription will expire soon. I got through to a consultant who informed me that there are now new rules and that a 30 day's notice is no longer required and that I should call a day before the contract expiry date to terminate the contract. I did not trust this consultant so I called the call centre again and spoke to a lady named Mbali who informed me a 30 day's notice is required. She put me on hold and thereafter said she sent through the notice of termination and that I would be contacted within 24-48 hours with confirmation. Two weeks has passed with no call. Prior to me calling the call centre, I had even sent an email to MTN informing them that I wish to terminate the contract. I did not receive a response so my next step was the call centre. I am going to place a stop payment on my debit order after this month if MTN does not terminate the contract as I have done my due diligence of informing them to terminate my contract. The call centre agents need to receive better training as they clearly are unaware of their rules and regulations
