Go to the Traffic Police office and they will inspect your car. Show them also the scratches on the car. They will issue you a police report. Your insurance company will repair the dent but will not pay for the removal of scratches. Do keep in mind that all insurance companies have a minimum deduction on all claims. Check with your insurers on this. For example, if their minimum deduction on a claim is say QR 500 while the actual cost of removing the dent and painting done on your car is a mere QR 200, it would be advisable for you to get the repairs done all by yourself rather than go to the insurance company.
