Unfortunately your dad has listened to the rumours of some taxi drivers who never have a clue what they are saying uber launched in Sheffield on the 5th of June how they have been doing NHS work for a few months is beyond me drivers saying they are targeting nhs work without a single uber driver done a direct job from the NHS it's rumour my friend your dad will tell you uber only deal with anything over e-mail there's no speaking to anyone part of uber on the phone a little inconvenient don't you think for a company to give a contract to someone they can't even speak to on the phone if there ever was a issue the uber system works direct from customers phone to the drivers phone any issue that comes from it has to be e-mailed and replied by uber however long that takes is anyone's guess in any city that uber operate in they have not taken contracted work.
