Useless network MTN absolute NO customer service

Very bad worst service i have ever encountered. I dailed 135 spoke to the call centre agent out me through to the credit controler they informed me that my account is handed over to VVM attorneys that was on 26/09/18 i phoned VVM as instructed VVM said my account is not with them they dont even know who i am. I phoned mtn 135 AGAIN the agents kept insisting i am handed over to VVM attorneys and i phoned VVM again and again they didnt even know who i was. I then was instructed by 135 mtn to wait 48 hours let the legal dept call me friday 29/09/18 i call them back again they say i must speak to vvm again i call vvm again vvm attorneys didnt know anything about me. I then called 135 and spoke to eintjies he said he will sort it out i must pay 1815.32rand then my account is up to date and can be cancelled i paid that full amount but his email adres i have is not working so i sent it to mtn vryheid branch (they were friendly and helpful) today 01/10/18 i get a call from VVM that i owe them R3600 to settle my account? UTTERLY USELESS so i already made an agreement with eintjies on my account to pay R1815.32 i do that but NOW im handed over AFTER MY AGREEMENT OF SETTLING MY ACCOUNT
