UBER - ********** COMPANY

Called UBER twice on the numbers provided on the app for HELP, the first time I was told it is just for UBER riders, the second time I called they could not access my account due to technical difficulties. I have two amounts reflecting on my bank statement that is unaccounted for. No receipts for those amounts were emailed to me. The amount totals to R775. **************** and **********. How can a company get away with this??? Oh and guess what, they also don't have a visible email address to record below. Ghosts!
