Hi there, recently my myvi got bang by a trailer/lorry, serious damage, facing a lots of issue for claim, hope that you all can give some advise

1. 08/02/2017 - My myvi bang by a trailer from the side
2. At first, my car was tow to my friends workshop, then I am advised to send my car to perdua panel due to it is 3.5 years car, consider a new car, can claim original parts
3. 14/02/2017 - Tow to Perdua Panel
4. 22/02/2017- Keputusan out, its the trailer fault, submit all documents to Perdua
5. Perdua claim advisor advise me to contact the insurance company myself, to ask whether I able to claim OD KFK, without further explanation, just ask me to call.
(To be honest i have no idea wat is OD KFK, third party claim before this)
6. I call Aianzz,
1st advisor
advisor said normally if involve commercial/public transport, cannot claim OD KFK, can only can on third party.
2nd Advisor
Can claim on OD KFK if the trailer is less that 10 tan. (But the trailer is more than 10 Tan in my case)
7. I call up perdua to inform what Alianz told me, and hope to claim on third party, but Perdua advisor told me Perdua did not do 3rd Party claim, can only claim OD KFK.

Its been 3 weeks, my car still in perdua workshop but yet to fix
So in this case should I repair my car in Perdua but claim on OD? or should I go outside panel to do 3rd party claim?
(someone told me, even outside workshop can claim original parts)

In the end, I ask Perdua to submit as OD KFK, if cant then will be OD.
Have no choice , because outside panel might able to claim third party faster, but my car damage is too serious, everyone advise to back to Perodua. Perodua guy told me actually they can claim 3rd party, but most of them don't want to do so, because it might take up to 6 months-1 year.

Aiksss, the trailer driver get 1 saman RM300, the victim have to lost NCD, pay for towing, have no car to use (2-3 months), take grab everyday
