Cellphone contract problem

My name is Joshua I have a serious challenge with a contract that I took with Telkom. I took a cellphone contract for R319 with Telkom on 2021-07-07 account number ***. We agree that the debit will be done on the 5th of every month. To my surprise there was no debit on the 5th August and again on 5th September. I then went back to Telkom shop on 5th September and reported that they are not debiting my account. I was told that my first debit is due on 5th October. I then use money in my account. When I woke up on the 6th September there was a bounce debit of R419 and this was after they told and gave me an invoice for R739 for 5th October. To my Surprise surprise on the 23rd September they debited an amount of R739 on my account.

On the 5th of October i received an invoice for R522 to be debited on 1st November, however on the 6th October there was a bounce debit of R739.This amount was already debited on 23 September. After that they blocked or suspended my number on the 9th October.

My number is still blocked and I am not getting any help from the shop or even when I call. They just keep saying I should hold and they hang-up.

They are messing up my life and I would appreciate if I could get assistance to solve the account issue My number is ***.
