Poor service and a lack of response.

<p>Two issues that I cant get a response from</p> <p> </p> <p>1 - my credit card expired. I was issued a new card and updated the details on my UBER account (it then gave me a success notification) and when I tried to use it, it claims my card is invalid. I tried to re-enter the card details a few times and it never made a difference. I have also noticed that it took off 10 separate small charges on my credit card account?</p> <p> </p> <p>2 - I had a free ride voucher. I used an UBER and paid cash. After the ride, i checked my notifications and noticed that the driver took the cash and used my free ride voucher at the same time.<br /><br />I e-mailed uber via the web site two days back on the first issue and have had no response. The second issue happened to me earlier and im as of yet to receive a response to that either.<br /><br /></p>
