Lie after lie and I sit with a bad credit record

Telkom how many times am I going to be **** to? Case is closed and I am told for the second time the data bundle issue is sorted and I'll be credited. Guess what. This month I get debited the full amount, no credit. Plus I get my invoice for this month and the data bundle is still there!! On top of it I have debit order bouncing because Telkom **** about the amount they will debit. Who is going to pay for all these extra charges? 3 bounced debits(R115 X 3) plus 3 months billed incorrectly! (R350 X 3) so Telkom owes me R1395! Plus who is going to correct my credit score with this negative impact! Again promised a call yesterday. No one phones me! I need someone senior to call me immediately! Or I'm taking this further as Telkom is just lying and taking my money. No impact to them!
