Unauthorised funds

I ordered food on uber eats on a Saturday night at two different restaurants. Instead of being billed twice I was billed 4 times . When I sent an inquiry about this I’m being told that it’s an authorisation hold . I know what an authorisation hold is , money went out of my account, it even shows on my bank statement .

Uber eats does not want to refund me. I’m truly disappointed in their customer service team, I’ve sent numerous evidence that Uber Eats took money from my account and they still don’t want to refund me.
