MTN sa debited my account a year after I canceled and settled my contract.

I canceled my contract with MTN South Africa about a year ago, I thought my troubles with them were finally over and I would not have to deal with their rude and *********** staff again until they debited my account a year after I canceled and settled my account with them. They debited my account on the 25th of January 2024, today I went to MTN store at Harvest place Glen Marais, I was told that my account was closed however the money they debited was for insurance on my router, I asked why am I being debited for a router that I have fully paid for and settled, the lady who assisted me didn't seem interested in getting my issue resolved, in fact she didn't have answers for the questions I was asking her, she then gave me a direct line for MTN insurance ***, Some lady answered the call and I went ahead and explained the reason for my call, she started by complaining about my line(looks like they are trained to say your line is breaking, I can't hear you clearly as soon as they hear a complain, which is one of the reasons I left MTN)

After hearing I wasn't buying her excuses, she asked me security questions which I gladly answered, she then asked me to hold as she was checking my account, she put me on hold for 19 minutes, the call started around 16:11 and she hanged up at 16:33, she lived up to my Mtn expectations, if they can't assist you they either sent you to a different department or hang up the call. Rude and unprofessional.
