I booked Tiago limited addition at Tata Motors Cars Showroom - AM Auto, Narwal · Ground Floor, NH 1A, Bypass Road Narwal Jammu 180004
But Due to problem in bank case i can't able to buy. The booking amount is 12000/- Rupess. Now I want refund of my booking amount. But no one is intrested to help for my refund. I contact one of There Salesman. Every Single day. But he delay again and again. And he did'nt mention for any booking cancellation deduction amount.. please process this request asap.
