L&t Finance — L&T Finance delivered a two-wheeler with wrong Register number

My brother-in-law bought a scooter in L&T Finance through online. They delivered a vehicle and NOC from L&T Finance. When we check this at RTO office for registration transfer, they found the registration number is not matching with Engine and chassis number.

Delivered vehicle details :

Reg. No given by L&T - TN12AP6324
Engine No - E32SE0312954
Chassis No - ME1SEG441M0022441

As per RTO office confirmation, the registration no for above mentioned Engine and chassis no is " TN12AQ1540 "

Buyer name - S. Subash
Agreement executed on - 21.3.2022
Mobile number - [protected]

We may need the correct Reg. No from L&T which is TN12AQ1540. We were checking with L&T agent Syed, Gayathri for long time but we don't get proper response and update. Please check this and provide proper details ASAP .

I raised 2 tickets on behalf of my in law.

Case# 16914832
Case# 16581919

But no update from L&T
