Assuming, you get delivery by Dec 2021 end, this KIBOR + 3% compensation would amount to Rs.26,000 approx.
I know this amount can never ever compensate you for the pain, frustration and agony experienced, but still if you are able to get this amount from Suzuki, it would be something done by Suzuki for the very first time in its history.
All I could wish for you is to get your Alto VXL AGS before the mini-budget, so that you don't end up paying the incremental GST, FED, & ACD.
