DEBIT ORDER IRREGULARITIES!!!!

Last year December 24th,2019, my monthly debit of R319.00 was returned due to insufficient funds. Telkom then ran another debit order of R319.00 on my account on the 2nd of January 2020 which was successful. I was very surpirsed when the debit order due on 25/01/2020 amounted to R790.70 which they put through my account. When I called Telkom I was advised that their system only picked up the payment of the 2nd of January 2020 on the 22nd of January 2020 , to date I haven’t been refunded the extra money they took from my account. To make matters worse when I called them again today I found out that the payment they took from my account on the 25th of January 2020 of R790.70 is not even reflecting on their side and due to their systems not updating payments made timeously they have now set another bill for me for the end of February 2020 at R740.70. Calling their call center is worse as I was simply told to call back next week to “check if the payment is reflecting”, yet this is clearly an issue on their side. If it was me that had defaulted on the payment agreement I would have been disconnected if not handed over! REFUND MY MONEY TELKOM!
