Account overpaid by R2271. but sorry; no refunds

When I tried to upgrade my contract, the in-store Vodacom employee said I couldn't upgrade due to an unpaid amount - I paid the amount in front of the employee immediately.

It turned out there wasn't any unpaid amount. My account is in fact, 2 months ahead, due to the amount going off twice.

So even though it reflects on my account, the usual monthly amount is still debited as usual.

I've raised this as an issue with Vodacom's refunds department.

The amount was paid more than 3 weeks ago with no response from Vodacom.

Still waiting for feedback...
