Uber is one of the worst ridesharing services I have ever dealt with. First of all, for the last couple of days I tried to request a Uber and I keep getting an error message saying, "your payment is unavailable at this time." Uber knows that there system cannot afford to be doing things like this, especially when people depend on there services. This is how things get screwed up, especially when I needed their services today.
