TELKOM R202 *******, VERY POOR CUSTOMER SERVICE

Telkom invoice system sucks, they are out there to rob people off their last cents unnecessarily and I know because telkom is so useless, they won't even respond to my query. So today I just received my invoice from telkom, in reality I am not owing them as I have completed my contracts and have already requested them to close my contract, however last month they sent me an invoice of R79, 99 on the 25th June 2020 for the last installment, my account had no money when they Debited, however when I realized that their debit order had bounced, I organized R80 and paid them via EFT on the 26th June 2020. 3 days later there was money in my account, they Debited my account and I just understood that it was probably tracking, so I didn't have a problem with it, I sent them a request to refund my money and ensure that all contracts are closed as per my previous request to close the contracts. No response. However today I received an invoice showing that they have received my EFT payment after the rejected payment but they charged me R202 for a bounced debit order which I am also paying penalty for to my bank account. Now I am puzzled as to why they charge this extra R202 if you paid your account on time? IS THIS HOW YOU ARE SUPPOSED TO BE TREATING YOUR LOYAL CUSTOMERS? PLEASE NOTE THAT I WILL NOT PAY THIS AND I AM GOING TO REPORT THIS TO THE OMBUDSMAN. THANK YOU FOR YOUR POOR SERVICES THROUGHOUT THE CONTRACTS.
