Universal Sompo — Didn't Received claim against my bike theft case from past 5 Months, Still struggling for it

Address:

Universal Sompo General Insurance Co. Ltd. Unit No 601/1602, A wing, 6th Floor, Reliable Tech Park, Cloud City Campus, Gut No 31, Mouje Elthan, Than

Claim number of my vehicle is CL22195873 and my policy number is USGI/WEBAG/0696156/00/B00. My vehicle was stolen on 17th August, 2022 and I am waiting to receive my claim from past 5 months.

They have responded with the Claim Repudiation Letter where they stated
“insured vehicle was not locked at material time of loss, which invited the theft loss held, which is also considered under breach of policy condition number 4, hence your claim does not falls in ambit of policy terms and repudiated in same grounds.”
But it wasn't like that my vehicle was properly locked and was parked in proper parking space and many more vehicles were also used to be parked there which was also visible in the whole video of the incident.
Amit Singh from Insurance company contacted me and told me after seeing 1:30-2 mins of video that the vehicle wasn't locked. But the whole incident took in about 20 to 25 minutes in different phases.
In some phases he was seen observing the surrounding, in other phase he was seen manhandling the vehicle and breaking the lock and in one phase stealing the vehicle.
following are the timelines.
1. 12:55:35 – the first time thief seen in the video.

3. 13:00:15
4. 13:00:47
