Complaint

I have been a customer for about 20 years. I was due for an upgrade on one of my contracts. Whilst I was deciding whether to upgrade or downgrade as I was paying a lot, I received a call from Vodacom that they were thanking me for being a loyal customer and we're giving me a gift. And for being a loyal customer my bill will be reduced to an amount I was happy about. To my suprise beginning of October looking at my app, the bill has gone up. I was not being gifted, It was actually an upgrade. I called for a reversal. The (gift) parcel has been collected. BUT will have to wait till end of the month to possibly see the reversal which means I still have to pay for upgrade I did not even ask for😭😭
