you haven't mentioned how was it lost... if you have that for service among Barwa shops, they must be liable to you. Or in case, you were a tenant in Barwa Village but then parked it somewhere, try to check with the village attendant or have a buzz with the village security perhaps they've just relocated it.

but if in case it was lost on your designated parking, report it to the police right away. probably a review of hidden cameras on the village might ensue for spotting of your quad.
