MTN SO CALLED CUSTOMERCARE AND SIFISO THE WORST!

Poorest service I have ever received. I have done an upgrade in May 2021. Since then my bill is a mix up. I have been asking the retention agent Sifiso Mntungwa to fix it. I have send exactly 37 mails to him and cutomercare at MTN without any respons. Not even a supervisor. I had to pay x5 R45 out of my pocket to reverse debit orders and then they have the odasity to charge me R11.00 because the psyment did not go trough. I have begged and screamed. Nothing is being done. They have no interest in their customers. I refuse to pay any account now until they contact me and sort this problem. Sifiso and his team is the worst. Keep on making promises but not keeping them. I am a fool in believing. Not anymore!
