Incompetence of Telkom Mobile accounts department

Telkom mobile's accounts department in completely and utterly ***********. I cancelled my Telkom LTE on 30 March 2021 and received confirmation that this cancellation was processed for the 1 May 2021 (i.e. cancellation fully completed). I was duly charged by Telkom for May 2021 (incorrectly) and was told by a Telkom representative that this would be rectified on the bill for June 2021. However, the account for June is a COMPLETE AND UTTER MESS!!! On this account I was charged for April (AGAIN!!!) for the LTE, the overcharge for May was not removed. In addition, I was suddenly double charged for my telephony (charged for April and June for both). NOTE: My account is paid by debit order and therefore the April account was paid at the correct time. I phoned Telkom the morning of 7 June 2021 and spoke to Nthabiseng (ref ***0) and was told it would take approximately 72 hours for the account to the corrected - I should have received communication indicating the corrected debit order amount for 30 June. On Tuesday 15 June I had still not received any information from Telkom and phoned again (Nompumelelo - ref ***0). It seems that in the time from Monday 7 June until Tuesday 15 June no progress had been made on my account. How is this possible? As things stand it would appear that Telkom is planning to debit my account with four (4) times the correct amount due to an error on their side and they are completely incapable of fixing this issue. I would not recommend that anyone expose themselves to this company!
