Tata Motors — tiago pre booking

Hi this is m. Shyamalatha from khammam - telangana. Here i booked tiago xt in venkata ramana auto showroom. At the time of booking they literally confused me to book the vehicle by telling this is tge last vehicle and next will comes in september. So i paid for it. Now the problem is financiers doesn't allowed me to take bank loan due to existing loans are higher than my annual income. At tge time of booking they told me we will refund you the amount in two days if cancellation happens. But now they saying we will deduct 1000rs cancellation fee. For what?? And remaining amount will takes 15 days time they replying. I'm sure definitely i don't buy any tata car in future by getting this type of rude attitude from tata employees. I want my money back till monday evening. Otherwise i'll go with my according.
