giv 1 last warning a sms or wat to him saying if he dun pay up the balance or wat you going to report to police. anyway u have wasted more den juz the $$$ for repair - u wasted lots of time. this type of ppl u go easy on them they think u good to eat..
actually i dun think juz getting back the $$$ cover all ur lost.
if i were in this situation, in the 1st place i will do a house visit. talk to his parent direct and not let him drag. but u are kind so u giv chance hoping that he will keep his words but now it shows that he is like abit not sincere.
go to the police let him jialat jialat.. if ask why u now den report juz say u wanna settle this privately loh but now he liddat leave u no choice.. they shld be will go check if he gt license or wat anot.
he wanna save the other half of the cost let him pay for more for his deed. the other half u shld be able to earn back in time. lucky u not injured if not i dun think $$ can cover the suffer that u endure.
make him pay for his deed if he does pay u back still go to the police.
take care..
just my 2 cents
