Telkom contracts

Pathetic service I received. Telkom contracts it is just a ****. Took phone contract 19 August 2020 and I was informed that since I took it mid month August will be pro rated. Meaning end of September my installment will be much high to cover August, did not have any problem with that at all. So my last installment was or supposed to be end of July 2022. I went to telkom store to cancel contract on 19 July 2022 knowing that end of July should be the last installment To my surprise end of August 2022 debit went off on my account, I went to the stare to enquire and nothing happened. I reversed the amount cos I wanted an explanation. Tried several available portals to voice my concerns but on several times I was told I did not cancel my contract despite me giving them the reference number I got the day I canceled my contract. September they did the same, I went to the store again today to verify if the contract was canceled and they confirmed that it was on 19th July. For now no one is willing to explain why was I billed for August even though it was prrated at the beginning of the contract. Tshepo Ntsane just hangup on me while chatting when I asked for explanation and he/ she is not the fist one to do that. I really don't want anything to do with telkom
