dont worry.  you can ask them in english about whose mistake it was ? if you have any problem, then you can ask them to recifity the fault.

After getting the paper for repair only go to any workshop and get the work done.  usually if it is not you fault, then the insurance company of the person who hit you have to get it repaired for you.

Otherwise if it is mentioned that is your mistake, then you have get it done at your own cost. Be careful. You can take any friend who knows arabic or any PRO can help you in this matter.
