I just need a car for work

I’m just a worker in Hong Kong, during the past few months ,I fully support our students and teenager to fight for our freedom and democracy, but last week, I drove my car passing through the road just after a confrontation in Tai Wai , a brick which was placed on the ground hit my car’s chassis, and cause the engine oil leak(I figure it out on the next day) Even though I get out from the car and check immediately, but I can’t found the problem at that moment. On The next day, I drove my car to work ,the engine light was on , and it can’t move anymore, I’m just a poor man , lean on a third hand car to go to work. I have no money left . So please help me
