Vodacom payment

I have a Vodacom contract and my line was suspended on 03/09/22.Full payment was made on 31/08/22.I was told my Vodacom customer care that the payment does not reflect on their side and there is nothing they can do. We should email our proof of payment to Vodacom and wait 24 hours for a response and thereafter the line maybe reinstated in about 2 hours. Payment was made at a reputable Vodacom store.
