Inaccurate amounts showing on what I owe

Vodacom hasn't debit my account since November 2022, I started making manual payments to them in Dec because I thought they'd debut which they did not. I paid for November and December and I have been doing manual payments on a monthly basis since then.

I contacted their service department because even tjo I made payment in March 2023 the balance did not update on the app, I was advised by a consultant that my account is not in arrears and is up to date however this morning I wake up to a sms informing me that I owe over R1000. I have my proof of payment for every month and I have sent a email to the support team but did not get any feedback.

I'm very disappointed with this service and it's not the first time I am having issues with vodacom. All these "missed debit orders" due to faults on their side is now affecting my credit record as well because even though I make the payment it still reflects on my report that it was a missed debit order.

The lady I spoke to even confirmed my debit order details and all was in order I honestly don't know what to do anymore
