My apologies for the late response Wan. Sibuk sgt2 sampai terlepas pandang your posting :4: ....
My take is, just change the plate number to the approved one and go for the inspection as required. If you have done so, usually they will "let you go" with a warning. The only thing I am sceptical is the summons for you to go to court. Why the need to do that? If need to do that also, just go and face the judge if they do want to fine you, dont forget to appeal (being a first offender) and give a good reason to lower the fine.
Never pay any runner any "service fee" coz you will never know for sure if they can do wht they say ... anyway its wrong ... Frankly I want to see the summons they issue you to really know what the summon is for ...
Cheers.
