Tata Motors — Tata tiago delay in delivery

Address:

Chennai, Tamil Nadu, 600100

I made a booking of tata tiago revotron xz (petrol) at concorde motors, omr, chennai on 07-may-2016. the order number is so-ccdche-rct[protected]. i made an advance payment of rs.10000 also while booking. i was told by the dealers that, the car will be delivered within 4-5 weeks. but it is more than 10 weeks now, but the car is not yet delivered. i have raised a complaint at tata motors, but they were not able to say when will my car get delivered. they just said "your car will be delivered soon", which i am hearing for over 10weeks but no action has been taken yet.
