Uber took my money from my account, claiming that I owe a trip when there's no trip I owe.

Uber just deducted money from my account. When I ask which trip did I owe, they won't tell me but they keep telling me that there's a trip that I did not pay for. I have been having back and forth conversations with them but they can't tell me which trip is that and the date of the trip. I have tried to explain countless times that there's no trip I own but they have gone to an extent of taking money from my account.
