Refund

Last month I recieved a wrong invoice from telkom for the amount of R433.84 instead of R231.14. I called them on the 11/06/2018, spoke to Lerato she said she will log a case for me to dispure the debit order rejection for the amount of R 202.70 (case no ********** 2). On the 12/06/2018,I called again to make a follow up, I then spoke to Nkosi Khona,he confirmed that the case will be resolved and assured me that they won't debit me that R433.84. On the 20/06/2018 a debit order went through for the same amount. On the 21/06/2018 I called again and spoke to Jabu,he said they will refund me the R202.70 back and it will take 72hrs to reflect into my account.I then logged a complaint with icasa becuase my query is still not resolved.On the 26/06/2018 somebody from telkom called to confirm that my telkom account is in credit with R202.70, I then asked her for that amount to be credited back to my personal account not the cellphone account.On the same day I received an sms saying case no ********** 7 has been resolved but I still haven't received my money back.I called yesterday & spoke to Sinenhlanhla,she promised me that the team leader (Lungilo) will call me back but it never hapenned.This morning I called & spoke to Shiryl who was very unproffessional, full of attitude and pathetic.She told me that the case is still pending,it's pointless for me to ask for a manager.This is very disturbing and unproffessional a query to take such a long time before it can be resolved.All I'm asking for is my money and they must cancel the debit order going forward, I will pay my contract by EFT monthly.
