Bad service by Vumatel

I'm very disappointing with Vumatel, i cancelled my account June and my last debit order was July but Aug and Sep they deducted and i was busy with the follow up for Aug then Sep they deducted again, they're saying my account is closed and the finance department cant do a reversal payment but they are able to deduct money and i sen them proof, now the Agent (Salathiwe ***) is telling me to do a payment reversal and that will reflect negatively on my scoring profile. Level of professionalism is zero. 3/08/2020 i spoke to Masithembe *** 7/08/2020 i spoke to William *** 13/08/2020 i spoke to Zenanda Lusizi *** 5/9/2020 i poke to Nkosekhaya Zatu *** 11/09/2020 i poke to Amanda *** and Salathiwe ***
