MTN contract cancellation

For almost 2 months I have been trying to cancel my Data contract with MTN . When I made the call I was told that my profile is not indicating an end and they need to fix that. A call was logged (Ref: ***) I have been following up on this issue and every time I call with my money I’m being taken from pillar to post, if it’s not Retention sending me back to customer services it’s the other way round. I am sick of this, monthly debit is continuing on my side. What must one do for MTN to assist??? How difficult can it be for someone to cancel a contract? Today 27/06/2024 I spoke Siyabonga who works for Retention, because I voiced out my dissatisfaction with MTN he refused to assist me and transferred me to some useless person working from home and doesn’t have a supervisor. This is such a disappointment for such a big company.
