Debited twice for 1 order

I placed an order on the 20th of February and I was debited for the order however when the delivery guy came to me,vhe said it's a cash delivery however I was debited and was debited again for another delivery. I was debited twice and received 1 order. Apparently it's an authorization hold that will be cleared within 10 days however there's no way of getting through to uber eats, I did not get my money back. I'm unable to contact uber eats with regards to this issue. Pathetic service, there's not even a contact number or anything on the app. I want my money back immediately.
