I thought this was very practical until my card was fraudulently charged twice tonight and I discovered how ridiculously difficult it is to do anything about it! I saw the ride come up and cancelled the first one, but I got charged anyway because it was cancelled at the last minute - to the tune of £17! I emailed UBER support right away but they are not available during the late night, it seems. I have changed my password and sent another email asking to delete my account but am afraid I will get charged again despite it all. Why is it not possible to take the credit card off the site? I don't want to go through the hassle of cancelling my card when it's just an UBER problem. If the site just offered that option I wouldn't be deleting my account. But now I'm totally turned off UBER and will stop using them asap.
