UberEats poor customer care

I placed an order at a restaurant on UberEats on the 21st of March, the money came off my account and then the restaurant cancelled my order. We placed another order for food and this money came off my account too. But the money for the first cancelled order hasn’t been refunded to my account. It doesn’t give me an option to click on any help options and I can’t get through to any customer care at UberEats - which means they’ve basically ****** money from me and I have no way of getting it back. I want the money refunded to my account ASAP.
