Nissan Motors — Refund of Excise Duty

Address:

Thane, Maharashtra

I purchase a T permit car from Ritu Nissan Thane in Oct'16, I was about to received Refund on Excise Duty but now they are denying to refund the amount.
I purchased it through Laxmi Group (Vashi) who deals with Nissan directly, however, Laxmi group is also not aware of why there is no refund on Excise duty. When I asked the about the refund their executive Mr.Navin told me that they have stopped giving such refund, but while taking delivery Ritu Nissan had taken my signature on relevant Excise Document to get the Refund.
