Did you get a pic of your car after the incident?
I think it's a tad late now to do anything about it.. doubt RTA would give confidential information.. and besides, with his licence number you can't get to his company anyway..
Police should of been called at scene of accident straight away.. cause they do a report which indicates time and a recount of what happened so they can use that for like, insurance, rarara... Doubt they'd get off their asses now
I'd try the company although they might cover for him
And have you done your own job on it? If you've sprayed over it.. I dont think you can get a claim off him.. even if your car is starting to rust n crap.. I really dont know what you can do for sure..
Did you even ask which insurer covers the boss's company? Cos unless you can get hold of the actual owner of the truck.... *hmmm*
But yer, you left it too long, think it's too late in my opinion...
