Tata Motors — about hsrp plate

Address:

Maidan garhi chattarpur

Dear sir,
I had purchased a vehicle from treo tata motors safdarjung delhi. My registration is from himachal pradesh and i had done it. I receivead adocument for number plate from rto which i had submitteed in dealership. They are asking for 2000rs for number plate. But i had read that govt had made a amaendment last year that dealer had to provide hsrp plate without charging anything. Becauuse hsrp charge is already included in vehicle cost.
So what should i do now.
