I use adamjee and have never had any issue with authorized center. My Toyota corolla had an accident and claim was of 80k+ no issues made i just paid the 10% depreciation on parts some 6k.
Last month my Alto had its windscreen had a chip mark from some random stone. took it to suzuki, also tail light needed replacement due to accident (rear ended by an elderly person) got it done again from Paksuzuki (Macca motors) no issue at all in claims Total bill was 22k for wind screen 7k for the tail lights and some other bumper clip parts total bill 31k for parts and 7k for labor (bumper got repainted) no issues made i just paid the 10% on parts. So if they are denying you adamjee claim get your contact person online and give him a a good piece of your mind.
