I think I got scammed by the customer

So I picked up the customer’s order and was making my way to his location. He calls me halfway through and says “I’m in North Carolina, I don’t know how my order was put through in Utah”. He proceeds to tell me to just mark the order as delivered so he can call customer service for a refund. I told him I’ll just call customers service and tell them the situation. Of course customer service was in another country because they didn’t understand anything I was saying. A few hours later I get hit with a fraudulent warning through from Uber.
