Volkswagen India — Extended warranty denied by Volkswagen

Address:

Pune, Maharashtra, 400095

I purchased skoda rapid from senator motors, mumbai. At the time of purchase itself i opted for extended warranty for which senator motors has duly given me a debit note.
Sometime after receipt of the car, senator motors closed down.
I went to another dealer jmd auto for service. I informed the dealer that i have purchased the extended warranty. Their response caused me to become suspicious. I therefore sent scan copy of the invoice to jmd auto as well as customer care email ids of both skoda as well as volkswagen. All 3 did not respond to the email and 2 follow up emails. I have now received email from jmd auto saying that the standard warranty is over and that i should purchase extended warranty.
This is clear fraudulent practice on the part of the company and its dealer. How can the company so shamelessly deny me something which i have already paid for.
