I just call and ask for a cab. They told me they will be there in 20 minutes.
Because 20 minutes was not enough for me to get ready, I call again (after five minutes) and said : Can you move the time to 50 more minutes...
The answer: JUST CALL WHEN YOU ARE READY and they hung up !!
So rude.
Never calling them again. You can see why they have 2 stars here
GO UBER
