No response to my report of unknown charges to my card.

I had 3 unknown charges to my credit card, which I contacted Uber about, besides the standard automated reply, I received no feedback whatsoever. After the first one I contacted Uber, no real response, so I left it believing they would sort it out. They didn't, and my card was debited again. So I removed that particular card from my profile. No problem for Uber, my second card was charged a day or 2 later. I have now removed all cards from my profile and allowed cash only. Surprise, surprise I have had no more unauthorized charges. Really glad we have options.
