Tata Motors — Tata-Tiago/Purchase related issue

I have purchased Tata Tiago from Sagar motors on 31st December 2020 during year closing by taking car loan from Sagar Motors. I am working at noida and looking at covid 19 pandemic scenario, I took the decision to purchase the car. From Jan. 2021, my emi on car loan began. But this purchase have put me into highly dissatisfaction and frustrated situation, where for one or the other reason my car have not been released yet for my personal use. I am still following up with the vendor. Will the dealer going to bear the interest I had to pay in Jan.and feb. 2021 as a loan emi.Does tata allow the vendor to delay handing over of purchased car. I was not expecting such an unprofessional dealing by the dealer who is serving in a capital city. I would certainly not going to recommend the dealer to my family and friends, as I do think that as a customer I have a right to have a benefit of timely delivery which had been taken for granted by the dealer . Also would request Tata motors to take action on the dealer unprofessional attitude towards poorly timed delivery and complete more than one month delay.
Please help in getting earliest possible delivery of my car.
