Frustrated and Still Haven't Received my Online Order

It's going now for the second week and I am so frustrated with Vodacom. Even though twitter always reply's to my queries it still haven't been resolved from the 12 July 2019. I ordered a Samsung A50 online and still haven't recieved it. Vodacom tells me they can't see my order on they side even though I have received an order number and copy tax invoice from Vodacom that my order was successful plus I have send a screenshot also that show's my transaction is complete.. Have send proof of payment on numerous accounts to Vodacom on twitter that payment was made. I contacted FNB again because and they said they cannot send proof of payment as it was done online on Vodacom's website. I have sent a screenshot showing that payment was made from the credit card, as FNB said that is all that can be provided to Vodacom. My last resort to possible solve this would be to go to 702.
