Tata Motors — No delivery of booking vehicle

Address:

Theni

Sir, I booked a tata tiago xt 2020 on 09/10/2020 at Chima TATA, Theni, Tamilnadu. They assured to deliver the vehicle in 40-45 days. But till now on 21.11.2020, no engine no./ chasis no. has been shared. If I ask them, they are telling "we are waiting for allocation" only.
I really disappointed with their answer. Looks like my wish to buy a car will go away.
So, kindly look into this matter and arrange to deliver the vehicle as soon as possible.

Thanks
