complaint against Telkom network mobile

So I have hearing a lot of stories about Telkom not treating their customers very well, and never knew I will also be one of them. On the 15th of October 2021 an SMS notified me that a double deduction on my contract I have with them was initiated. Now because it is weekend I thought let me waiting until Monday or Tuesday to investigate the matter. Remember now I have never been in arrears with my contract and they always deducted on the 25th of every month. Yesterday I visited their stores in Emfuleni in Cape Town, the manager said they will call me. I was told that I need to wait for 14 days as the debt collection agencies need to see what happened. I was very disappointed as I never skipped not even one month and they do this to me. Very disappointing service indeed.
