Hi I am banking with FNB

Hi I am banking with FNB. There has been transaction on my account that I was not aware of due to being at work at that time. Logged on to my account and R1320 has been deducted by FLW*UBER EATS, cancelled my account right away. Called FNB and I was told that I will not get the money right away as the investigation takes 7-30 business days as it’s my card ending with 1135. The lady on the phone was not helpful at all. I have proof of my UBER EATS ACCOUNT , the last activity was months ago, also I always use cash on it. FNB has a way of routing you to their APP to accept that payment going out so if I was the one using the uber eats why did it not route me to my FNB APP to either ACCEPT OR DECLINE that transaction.
