Unauthorised/*****ulent Transactions

So I was de*****ed on your platform by someone who managed to obtain my details *******ly and proceed to place food orders with my bank card. I reported the matter to my bank and they require a cancellation letter of the transactions from your business in order to process my refunds however I cannot reach the business because there is no email address available to do this easily. The support@uber mail is not helpful because it returns a message that it’s not monitored and refers one back to the uber website. It seems as though I need to create an account in order to do so however I am not interested in creating an account. Can somebody help in providing the email address to report this matter to so I can get assistance.
