Sai Service Station — misleading information about insurance

Address:

chinchpokli, Mumbai City, Maharashtra, 400012

Date 11 Feb 2019
Location Lower Parel Phoenix mall, Sai Service
Car Number: MH01DB3478
Incident: I went to repair my side mirror under insurance, but your executive asked me not to cover it under insurance else my no claim bonus will go.

According to Executive: Insurance Amount ~18000 and I might need to pay ~13000 as no claim bonus, getting benefit of 5k

Mirror cost: 3880

He provided misleading information by not telling us the Depreciated insurance value

So in reality:
Insurance premium: ~15k
Insurance premium with no claim bonus: ~13500

so there was benefit of only 1500 rs

if I would have repaired the mirror under insurance

I would have get it fixed in (1500Claim bonus + 1000 Charges) = 2500

I made a loss of 1400 rs

Now I would like to get my 1400 Back in anycase, else I am going to claim a consumer case against it, as I tried explaining Lower Parel Service center about it and they are not giving a ### about it
