MTN

I took out a wifi contract with MTN telesales. The router and sim were faulty and was sent back by our local MTN store within 5 days. The contract was cancelled but another amount was deducted and I reversed the debit order and it cost me R30. Since the cancellation of the contract on the 8th August 2024 I battle to get my refund. I took out another contract of R269. They double checked at the store that the previous contract was cancelled before I took out the new one. I still battle to get my refund and today I received 2 bills. One for R1932.15 and one for R593.46. The debit order is going of on the 4th September 2024 and if I reverse that one its going to cost more. MTN request the same info over and over but no refund and accounts department keep on sending bills. Its been a month that I just hear the words.. Sorry for the inconvenience and i thecsame breath ask the same info and the same reply. Within 2 to 3 days... Nooo already a month with everyday follow up.. What more do they want?
