Hyundai Motor India — Refused to sell car to disabled person

Im paraplegic (wheelchair user).

I was planning to buy i20 but vishal hyundai panvel dealership refused to sell me as rto procedure for tax excemption is a lengthy process so they cannot sell me and asked me to check with mumbai showrooms which was very disappointing so i went to kharghar showroom they didnt refused bt said they are not aware of the process so they will check and will let me know but even after following up with them they didnt had any answer and no response from them.

This is very disappointing that dealership and their agent dont have any knowledge and also not helping me or guiding me.
