Similar thing happened to me. Uber put a random charge on my card. I totaled up all my orders/invoices and made sure it didn't belong. Then fought with them for a month, every time they either refused to help or told me it must have been someone else in the family. Luckily Discover had my back and refunded the money immediately when I asked. Never used UberEats again.
Either way, just lay these transgressions on the heaping pile of Uber's toxic business practices. Stealing self driving secrets from Google, maliciously targeting politicians and police, and now just petty theft.
