The buttons don't work

Alondwe, we can't read your mind. You're going to have to give us more to go on if you actually want help. Mobicel makes a lot of phones; we need to know which one you have, so add the model number to your question.

In addition, you'll need to be more specific about which buttons don't work. Are you talking about the volume buttons, the power button, or something like an onscreen button? Tell us more about what the phone is or isn't working.
