Debit orders running on wrong dates and then they penalise you as the user

When I signed the contract with telkom mobile, I selected the debit order to run the last day of the month. Then they go and run it a day or two before the end of the month and there is no money in the account. Next invoice I am fined R100 for the debit order bouncing plus the bank levies a penalty of R75.

This happened twice now, and they even state on the invoice when the debit order will be run, but they still don't stick to that date, they sometimes run it earlier. I have sent in two complaints via email starting on 27 Feb. I received a quick response requesting documents but then nothing. I sent a second email, also got a quick response saying the system is very slow and they do not know how long it will take, but it has been almost two months no. I also called them and I was told that I would receive a reply by that Friday, but this is also several weeks ago.

The last time the debit order was returned, I paid the invoice via eft the next day. Two weeks later they tried to run the debit order again even though the payment was reflected on my statement. It bounced again and then there is a random debit order of R8.5 from time to time, who knows what that is for.

Be careful, rather pay your invoice via EFT, do not give them your banking details. I will now try to stop the debit orders and pay via EFT. I feel like going to FNB and reversing the de bid orders where I was overcharged.
