Complaint

I am experiencing abuse from Telkom. i have not skipped any premium, there is one month where they never took premium while there were funds available, and then few days later they double debited me indicating that there premium did not run as plan hence double payment. when contacting their consultant, they confirmed that indeed it reflect that there were funds available at the time where debit order was supposed to go through. i reversed the funds and made a payment of what was due to them. now i constantly receive invoices saying i owe them 540. my premium is only R145 and like i said i have never skipped paying them. i spoke to one of their consultant who requested me to email him proof of payment for the month their claiming i never paid, to date i have not received solution.
