*****ulent activity

I have 3 charges on my bank statement from Uber eats for food I didn't order or receive. I ordered a Uber trip and someone simultaneously placed 2 food orders on my account. The activity doesn't reflect on the Uber app but the reference on my bank statement is Uber. This happened 2 days in a row, I've logged the *****ulent activity with my bank but I am very unhappy that the Uber app is not secure.
