Tata Motors — Altroz DCT broke down on road after 14 days of delivery with DCT Fault Error

My Altroz Saga:
I took the delivery of Altroz XT version on July 7th from one of their dealers in Trivandrum, Kerala. On exactly the 14th day of taking the delivery with just less than 50km driven so far, the car stopped on the highway with a "DCT FAULT" error in the middle of driving, with the gear change not happening and loud noise coming from the car, Car not speeding up beyond 30kmph, and too much congestion to move. Finally, we had to call the RSA and tow away the car. Even the service people found it difficult to move the car to the towing vehicle. Sent multiple emails to customer care, tried to call multiple sales people, no responses from anybody yet. One week passed, guys from Tata Motors landed in Trivandrum to troubleshoot, even they are not able to find out what is going wrong !! Here I am sitting desparately, with 10 Lakhs lost in the sea buying this car.. There is no solution in the vicinity, and days passing by.
