I had an accident like four months ago...I was on...

I had an accident like four months ago...I was on motorcycle at Al Raynn round about signal then a car 🚗 wanted to join my lane and knock the car on the back door and fall down with light injuries then police came in and ambulance took me inside for first aid while police officer taking my details and finally I was taken to the hospital where I an officer of the ministry of interior brought a certain pepper to sign which was written in Arabic language when I tried to ask him to translate it in English he told me that there is no problem against me but just only to complete a report about the accident with people who where involved and then I signed it ...now just recently I have received a Summon calling to the traffic court which I attended on last Tuesday court asked me what I was happened and I told them and told to go .. after four days I received another massage telling me to visit the verdict execution department of MOI and I went there where I found that I had to pay fine of 5000qr because I cut the red light signal.... which I didn't done at the first place... after receiving the prepare I was advised by the officer to do objection to Al sadd court and told me to go back on 14/09/2021 but I really don't know what exactly I should do five thousand fine is too much for me mostly on the case which I didn't done...I wonder why they didn't put the violation on the motorcycle plate number just like over speeding violation
