Tata Motors — Regarding delivery of new booked tata nexon XM petrol

Dear sir,

I have booked tata nexon XM petrol dated 10th of October 2020 in patna from ananya auto agency pvt Ltd. The dealer has committed that we should delivered your car with 5 week. But now they are telling that now it will took 3 week to delivered the nexon XM petrol car. I need the car on 14 th of November 2020.but the dealer is not giving any confirmation. They are only false commitment. Is it tata customer service???? It is hearting my sentiment... If I will not get the nexon... I will leave the brand(Tata) for ever...
