Advanced voucher already paid but still attempting to debit my account!!

On the 20th April I took a voucher advance of R100 on the Vodapay app. Paid it back 4th of May. Til today Vodacom is still trying to debit my account of this R100 I called customer care and asked if they could allocate this payment to my profile and i was advised they could not. The person i spoke to is Percy and he assured me that it does reflect as settled but it just needs time to clear on the system. How long does this take to clear ???? We are going into the new month now and Vodacom is still trying to debit my account, I had to move my money because I'm sure if they can't even allocate this payment, a refund will be even more of a hassle. I want this sorted out ASAP as I pay fees everytime that it's declined!! - This complaint I laid on HelloPeter on 28th May.

I then received a call from Marvin/Marlin who works in the complaints department who said he will said me an email and I'll have to respond onto that email with proof of payment, which i did. On the 6th June i asked for feedback and to this day no resolution, feedback or anything?? Is my query not big enough or just no5 important enough ? I literally had to move my money into a separate account because every day Vodacom is attempting to debit my account for which i am paying declined fees for!!!! Truly disappointed with the services or rather no service received cause it seems no one wants to help
