Every time I move my handle bar left or right the wheel turns in different direction
Sounds like the handlebar stem is loose. This is an extremely dangerous situation and you should go immediately (pushing your bike or taking it in a car, but not riding it) to your local bike shop to have it looked at.

The fix is easy and should take less than 5 minutes (and only a few dollars/euro if they charge you at all), but again it is critical that you get this repaired.
