Bad Service

I am really upset, but more than anything else, disappointed with the service I’ve received from MTN. I have been calling for close to three weeks now regarding cancellation of a migration that I never approved of. They opted me in for a migration that I never authorised. I am more than irate about this whole situation cause MTN has not even made any means to rectify this. Every time I call, they tell me that they’ve escalated the matter and that I should call after 3 working days, and when I do actually call after those 3 working days, they inform me that no one has escalated the issue yet. Like, where’s the truth in that?? At this point, I don’t even want to be refunded. I just want the migration to be cancelled and nothing else. Thanks.
