Paytm Mobile Solutions — regarding transaction refunding

Recently i proceeded a transaction through paytm for mobile recharge. But it was not successful as i don't know the due of it. My money of rs. 145 was deduced from my account inspite of failure in my transaction. And i was notified that money will be refunded within 7 days. So i waited until that. But now it is about to reach end of 2nd week from the date of transaction. Still money was not refunded. I request you to take steps to resolve this and make a way to refund my money.
