Anyone BUT MTN

GO TO Vodacom or CELL C is my Advice. MTN/MONDO are the Worst. I am nearly 4 months in and after having to reverse 2 debit orders I am still receiving invoices. My main concern is that MTN/Mondo have blacklisted my name in no error to me. When I call as the automated emails tell me, i get put on hold and transferred from one to the other or I select the number and eventually a message says " we can see this number has made many attempts to get through please email 135@........ which I get no reply from and nobody seems to have heard about this email. I have had many contracts and accounts over the years and this has been a horrific experience. People don't email/call you back. All I keep asking is that they do what the lady that called me in January said was going to happen. Cancel the contract with no charges due to the sales error on their side and send me a letter of proof that my name is not blacklisted due to this experience and my having to reverse the charges taken from my account. My only next step is to contact the Omdubsman and hope that they can assist as i have asked for a superior member to contact me so we can resolve it. I have mailed customer services at Mondo and MTN many times as well as the complaints email at MTN and nothing happens. It seems to just be automatic responses.
