***** on my account

I noticed unauthorized transactions on my account on the 14th if January.These transactions were from Uber which i have never used.I came into the branch to report these transactions.The consultant assisted me to cancel the card and also advised me to phone ***** to log a ***** case which i did.Then on the 21st January i received a notification another notification of R583.89 from Uber Eats again which I have no knowledge of.The most concerning part is that this card was still to be drlivered and not activated yet.My question is how can transactions be done using a card that is still with the couriers and not even activated.If this is not an inside job done internally then i have no other explanation.M very dissapointed in fnb as I have been with the bank for over 12:years after moving from Nedbank due to poor service.I need an explanation how these transactions were done and also my money to be reversed back into my accoun***** a shame that i will have to close my account after this has been sorte.
