malaking tama yan ah...

if he's telling you na you're overcharging, personally, i'd give the operator the finger and ask him why the hell would he complain, one his employees did damage to your car due to reckless imprudence and as such, caused damage to your car.

and that kind of damage, hindi pwedeng pukpok back to shape, lalo na for the affected suspension components, so it will really cost a lot. after all, you're not going to gamble your safety with substandard labor and parts (which will definitely be cheaper).

sorry, badtrip lang talaga ang mga ganyang incident :D
