Paytm Mobile Solutions — amount got deducted but not refunded

I tried to book my ticket though paytm but payment got deducted and ticket was not booked and even its been 4-5 days my amount did not refunded! Seriously high time as i talked to them many times but there was a casual reply! And after having conversation two to three times one expect it to het clear but seriously no shame! What is this i mean???
