Hi.. need advice..

My car got knocked by someone and he admitted it's his fault.. both of us already lodged police report so I can claim his insurance for my damages..

from what I've read on the forum, I should be able to claim under OD-KFK, without impacting my NCD.. but weird thing is, my insurance agent is telling me that for my next insurance payment, I will need to pay insurance amount in full (without NCD), and the insurance company will rebate back? I'm a bit concerned because it kind of means that my NCD is affected..

anyone here faced the same thing before while claiming OD-KFK?

thanks in advance for any advice..
