VERY DISCARDED

I am not one to complain but I'm very disappointed in the service provided by MTN, I have been going up and down just to get a sim swap, the next thing I will receive is a deduction, paying for services I didn't even use. Their customer service is not friendly. On top of that I still need to pay R150 for the swim swap. Gosh the process is draining and frustrating .. After holding for more that 30 minutes on the phone I still have to wait another 24hrs..I've basically waited for 144hrs for this swim swap. I'm not even gonna upgrade anymore after the trash service. I called to block the sim but the person who stole it still had access to it, how? I don't know..
