MTN Cancellations bad service

Good day

I have been with MTN for over 10 years and i am shocked by the level of service received in the last 3 days. i have been contacting MTN cancellations department VIA number 135 on 2 March 2022 @9:32am and 10:21am and again on 4 March 2022 @ 12:29pm and 12:37pm, all i want to do is cancel my contract and move over to prepaid, the Gentleman that helped me on 4 March @12:29 said he is going to put me on hold while he verifies my details, after 7min of holding the call drops with no returning call. The lady that assisted me on 4 March @ 12:37pm had no clue what was going on, and said she can not assist me and will have to transfer me to a different department, and same thing the call dropped. The call center is so loud with people laughing and shouting at the background and makes the call so unclear. I need a supervisor or manager to contact me regarding my cancellation as this service is ridiculous. i Will in the meantime be contacting the Onbudsman regarding my Problem.

Cant believe i have to get to this point for a simple Task.
