MTN terrible service, MTN suspends my phone contract claiming that I missed payment for June and July 2020. They suspended my phone first time on the morning of the 26th of November 2020, just after I paid monthly premium of R1000 the day before. I called one of their consultants on 135 to check what's going on and he apologized after seeing my payment reflect on his side and then reactivated my phone. On the 4th of December, they suspended my phone and this time claiming that I missed payment for June and July 2020. I informed their Consultant that I have never arranged for payment holiday, and I've paid my phone hence it was working in June and July 2020. Furthermore, I told the Consultant that MTN will never give you free service for 2 months, you miss a payment they suspends your phone with immediate effect. Now is the 6th of December 2020, my phone is suspended again. I can't wait to terminate my contract with terrible service provider of 5.
