Ana, sorry, my confusion is about you not going to your insurance firm (instead of trying to handle it on your own, you do not know the fine print or speak the local language and most likely will not have the finances to go legal over the mandatory Qr.1,000.00 court fee ) and telling them about this accident.
It is in their interest that you get the max value.
Of course, the other person's insurance firm will wish to pay as lowest possible. It is their bottom line (Profit) which they show at the end of each financial year.
Each of these insurance firms have their paid lawyers to handle legal cases. Let yours earn their keep, You paid for it man, They have guys that speak a common language and know the loopholes.
All the best.
