Paytm Mobile Solutions — transaction failed while booking ticket at irctc from paytm but amount deducted

On 16-oct-2018 i booked ticket from irctc using paytm. However amount has been deducted from bank but process was in error and so ticket was not booked.
Today when i called customer care number mr. Manish kumar pick the phone and ask for the debit card number, atm pin and cvv number, which is not acceptable as this is secure information and not even bank demand for such information.

When i denied he misbehave and disconnect the phone. I am sure this was some fraud person and i want your team to check the matter.

Also let me know how can i get back the amount which had been deducted from my account.
My transaction id's were —

Amount 1, 921.80
Amount 1, 922.78
