PHONE STOPPED WORKING

Well, you aren't going to get Steve here. You can follow the troubleshooting procedures found in the iPhone manual. It can be found online at the Apple website. First you try to power the phone off/on. If that doesn't work, then a reset, which is holding the sleep button and the home button together until you see the Apple logo on screen. If that doesn't work, then connect the phone to iTunes and try a restore. If that doesn't work, then you can contact the Genius Bar at Apple. However, unsure if you have one there, you may have to make contact direct with your provider if they are the ones responsible for service.
