Payment of R800 still not allocated

I paid my account with a wrong reference.. Sent it to mtn over 6 times including customer service. Went in store and sent it to that mtn rep.. Forwarded it to multiple agents.. This was over 6 weeks ago.. Till today it has not been allocated.. I still get SMSed saying my acc is going to be suspended and that I owe MTN.. Pathetic network.. Would never recommend anyone join this unbozza network that claims to be so professional.. If you call after 5 agents are screaming at each other in the background and saying that the noise level is normal.. Extremely unprofessional.
