Worst customer service ever

I have an account with telkom, they decided to debit me every two months instead of monthly, then they put my account under collection and charge collection fees. They last debited me on the 19/06/24 even today my account is still under collection payment not allocated, ive been calling since tuesday they kept saying they will allocated payment.

i have been wanting to cancel my contract for last 3 month but i cant because my account is always under collection.

i spoke to 4 ***********'s consultants who drops the line on my ear when i asked for their leaders. Every time i want a team leader i get told they knocked off and the will call me whenever they get my call back request.

i was promised that Clive, team leader will call me on Wednesday, he didn't. i called again on Thursday was told Mr Magubane, team leader, he didn't. Today the 12/07/24 i called again payment not allocated still, i asked for team leader, i was told she is working from home and they cant confirm when she can call me.

what service is that
