Poor service delivery from MTN

My several attempts at cancelling a contract for a Sim upgrade on 30 May 2023 proved to be futile, and I was thrown from pillar to post leaving me frustrated and angry. My numerous requests to the branch where the contract was taken viz. MTN at Paddocks Mall, CPT, and to MTN’s Customer Care Dept. is pending apparently due to a system glitch. Furthermore the entire cancellation process is botched up due to conflicting advices received from both parties who amusingly are pointing fingers at each other! Eventually this matter was escalated on 1 June 2023 to higher management by the Cancellation Dept. for review, with no promised date to receive the outcome, although the cancellation has to occur within the 7 day cooling period beginning from 29 May 2023! If this period lapses the contract will remain in effect and I will be liable for incurred charges, which is totally outrageous! Subsequently I wrote to MTN complaints dept. on 1 June 2023 and anxiously await their response. Gauging from the manner this issue is currently being handled indicates that canceling a contract with MTN is almost impossible! Clearly their after sales support is poor to say the least.
