Uber site for BlackBerry still not working

I have used [URL Removed] for a number of weeks without any problems. I actually became a big Uber fan during those early days. Saturday evening when I logged into [URL Removed] from the brower of my phone (I am using a BlackBerry Z series) I get one of two options (a) a network error message (b) or I get as far as enter my log in details and if the map appears on my phone there are no Uber cars to view or an option to get a quote fare or to book a car. I wrote to Uber Saturday night and few times after that and I received replies but (a) a telling me to remove the App - someone at Uber doesnt read e-mails properly because if they did they would see I cant use the App for Blackberry. Another response said they have re-activated my account. Still not working on my phone (But, it does work on the home computer - which is no good when I am not at home and wanting to book an Uber) A friend, also with a Blackberry Z, is having the same problem and the received a message from Uber on Monday saying that they have a problem that they are trying to fix. What is going on Uber? Why is [URL Removed] for my BlackBerry Z not working and why cant I find a phone number to call you.
