Debit Order Woes

My vodacom debit order date was the first of each month, but due to the fact that my payment date changed, I changed the debit order date on from the 1st to the 7th of each month.

I purposefully did this on the 1st of May 2025, as that is my debit order date. Due to it being a public Holiday, the debit order for May was only deducted the 2nd of May 2025. So from my side, all is good, my next debit order date will then be the 7th of June 2025.

But I guess not, as Vodacom tried to debit my account on the 7th of May 2025 AGAIN!!!! After they received full payment on the 2nd already.

As I was not aware off this, the payment was not in my bank account, and the debit order bounced. So now Vodacom has the audacity to charge me R100.88 for the failed debit order, after the mistake was on VODACOM's side. Vodacom tried to debit my account again, after they received payment on the 2nd of May already.

When I queried it with Vodacom, they can't give me feedback on why the debit order was tried again, and when I will receive a credit note for the bounced debit order invoice, which I will not pay, as the mistake was on Vodacom's side.

It is really frustrating.
