Non delivery of vehicle despite of full payment

I booked Mahindra XUV 300 in Astro Mahindra before launch i.e on 15 jan-2019 because a kid was expected to be born . we welcomed our kid on 9-feb 2019 to this world. Astro made fake promises of vehicle delivery but could not make it in time , So I called Shuhul, automobile where Team leader Picked the phone and i was told that with in 12 to 15 days shuhul motors will provide me the vehicle. On that very day Sales executive visited my office with the proforma and i was briefed about insurance and delivery date. I Cancelled booking from ASTRO because of assurance given by SHUHUL. I received a call on next day from executive i.e on 29th of March that i have to pay full amount of 11.50 Lac as mahindra is going to raise prices. on 30th of March J&K bank transferred full amount to SHUHUL. Transaction ref No. dc121436. prices never raised after that. I made call on 12th April know about the status of vehicle, my phone was ignored by both executive and team leader. No body picked phone on delivery date of vehicle. I called customer care of MAHINDRA where i was provided with the phone number of Area sales manager, i briefed him whole story he instructed SHUHUL to pick my call and on doing so i was informed by SHUHUL through sales manager that vehicle will be provided with in one week. After one week i again called sales manager where i was told that vehicle will be provided on 10th of may. I visited Shuhul Motors and met general manager and owner where i was told that employees of the agency has made false commitment to me and status of vehicle is still not known as on 29/04/2019 as per telephonic conversation with Mr. General manager. I request what can be done for following points mentioned below. 1. Agency took full amount from me promised delivery of vehicle on 12th of April. Which was later postponed to ending April and again postponed to 10th May and still status is not confirmed as per (G.M) he says till 30th of may there is no guarantee 2. I am bound to pay to bank the installment of Rs 19000. I want to ask for what ? i dont have vehicle with me and my money is with SHUHUL motors. 3. I have been harassed again and again by SHUHUL employees. My mental peace has been snatched by unprofessional staff of the agency. 4. Many festive eves have passed by Navratras, ramnavmi, Baishakhi as well as akshay tritiya for which i planned to buy vehicle. I am still empty handed with no money and no vehicle.
