Paytm Mobile Solutions — paytm postpaid is not sending my money back and not letting me use that money for any purpose. i want my money back.

My paytm postpaid balance is 1143 rs. The basic spend limit is 750 rs. But last time i tried to pay my due amount and it mistakenly paid twice. Total balance is 1500 rs. Then i booked a train ticket from this balance but canceled it later. Now my total balance is 1143 rs. The excess amount is 393 rs. There and the basic amount of 750 is also there. I want to use that money and i want my 393 rs. Back. It says that i can use that balance for boking and recharge and some other purposes. But it's not letting me use it for any purpose. I tried many times to contact the customer care, they are saying that my excess amount will be returned in 3 days but it's been 2 months. I need my money back.
