Incompetency and overcharging at Telkom

*********** people working at Telkom. I changed my debit order from std bank to Capitec 3 months ago. and they still try to get money out of std bank as well. Now charging met ridiculous rejection fees of R222 each time.. I will not pay this as I have paid my account every month. According to me I am a month in advance. I sent them a letter from my advocat as well but no reaction or response. I also have proof of payment for every month.

Is this another ESKOM failure. SHould I rather cancel my contract.. I REFUSE to pay a rejection fee if they cannot sort themselves out and keep my info up to date.. This is so sad
