Tata Motors — Tata tiago not delivered even after 4 months and now they say vehicle price has increased

Address:

Thane, Maharashtra

I booked a tata tiago xz petrol model at the tata motors thane, ghodbunder road branch (Atulya motors) on 29th april 2016.. Dealer communicated the vehicle will be available in 1 - 1.5 months, its almost 4 months now the vehicle still is not available and i keep on calling every week the reply is only that we are trying our best to get the vehicle as soon as possible.
Recently when i visited the showroom the sales representatives said the tiago price has now increased and i have to pay the new price, this is realy disgusting of tata motors. I booked vehicle on 29th april 2016, price rise was in august 1st week, how could they ask customer to pay the increased price with no fault of customer. This is absolutely poor service, i am now going to cancel the booking. Would suggest no one to buy tata vehicles they are cheats..
