Tata Motors — Refund of money

Address:

Mumbai City, Maharashtra

Hi, i had booked tiagao from concorde motors mumbai, requested to cancel it one month ago, not received money till now, after rigorous follow up also, they said it will take 10 days for refund still not received & they are not responding as well.
It has more than a month now. This is not accepted from brand like tata that you are troubling your customer, next time we will not buy any tata car in future if this is the scenario
