I need urgent help. Last night, March 20, 2022 at around 6:40pm I placed my order for grab food. The payment was charged on my AMEX account, but the order was cancelled because there are no available nearby riders that time (as per grab notification). I really need the money, tried to use the help center but it was not helpful, I have been looking for a contact detail so that I could call the support personel maybe but couldn't find it in the app.
