Poor from MTN's

I'm sitting here writing this review frustrated by MTN's poor service. My phone nr was hacked on Thursday and the ****mer did a Sim swap as his enjoy to **** my contacts from watsapp money. As he is saying I'm in crisis. So I tried calling Mtn and I was told I couldn't be assisted on the phone because my Sim card doesn't have that nr at the back. So I ws referred to the local branch were I found small and arrogant boy who told me to go by a new Sim from PEP store and follow the instructions. I did as such but I didn't succeed so I called again to Mtn were I was told again to wait for another 24 hours after buying the new Sim. Then today after the 24 hours I tried the self service which told me the new Sim could be used and I needed to by another Sim so I called Mtn again about 5 or 6 times were my call was directed to this same lady who told me to call again because her system is offline. What's frustrating about everything is I wander if the ****mer also to go through these red tapes before he could do a Sim swap when he was *****ing my nr. What is bad and sad about everything is that the ****mer is continuing to ask money from my contacts and others have sent since they think I'm really in trouble. I can't even reopen my accounts because they sent OTP pins to my nr of which I can't be assisted with just a Sim swap just to block the ****mer from taking people's money because there are many networks which I could change to but I can't just leave this issue unresolved.
