Nissan Motors — Neo Nissan Ghaziabad Dealer - stockyard charges and insurance issue

Dear Sir
I booked Nissan Magnite XV (NA) on dated 17th Jan 2020, where Neo Nissan Ghaziabad Dealer executive Mr Prashant (Mb [protected]) assured me that he will range car as soon as possible. On 27th Jan i received a call from prashant and he said one car is available and he can arrange delivery on 1 Feb 2020 but that time i was not in the city and i asked him i can take delivery on 8th Feb 2020. then Mr Prashant said yes we can take delivery on 8 th Feb but you have to paid advanced money so that he can hold car for me then i transfered 1 lac rupees on dated 29th Jan and 1 lac on 3rd Feb. But when i visited 7th feb to neo nissan ghaziabad showroom then Mr prashant revealed that he had given car to someone else as you were not available to take delivery.
on the same day he confirmed me for 18th Feb and said he is arranging brown/black color car for me .
Now today on 17th Feb 2020, when my HDFC car loan representative shared DA (disbursement amount note) to him then Mr Prashant and his senior colleague told me that you have to pay Stockyard charges Rs 6500 extra and you also need to take insurance from Neo Nissan Dealership.
In offered quote :
Ex showroom 668000 + RTO 55870 + Insurance 28333 + Extended Warranty 12425 +essential Kit 2249 + 0% Dip insurance 5617 + fast tag 500= 7, 72, 994 (Seven Lac seventy two thousnad nine hundred ninety four)

in the lieu of I have deposited 3, 11, 000 and i arranged insurance from my HDFC collaborative bank so that remaining amount will be Total quoted 772994
less Insurance 33950= 739044 (insurance i arranged from my end)
advanced paid 311000 then[protected] = 428044 remains for loan disbursement

Issue /concern: 1) why i need to pay stockyard charges Rs 6500 extra as it was not mandatory and also not revealed in initial quote.
2) why dealer enforce me to take insurance from him as he is a car dealer not insurance dealer, every buyer has right to take insurance from any source.

For your kind reference I am sharing Quote for your necessary actions against Mr Prashant & Shailraj and Neo Nissan Ghazibad C47, Arya nager Indl Area Ghazibad and Neo Vehicleaids Pvt ltd C26 Sector 3 Noida, Ph [protected], [protected]
