Paytm Mobile Solutions — amount has been deducted from my savings bank account and the amount does not reflect in paytm history

Address:

Hyderabad, Andhra Pradesh, 500039

Rs.1500 has been deducted from my savings bank account on pos movies93333 at ptm*paytm app without my involvement.
Am dis satisfied with the paytm app as i had used my otp to make payment to institute of chartered accountants. But unknowingly it has been used for movies93333 at paytm app.
Refund me the amount of rs.1500 to my savings bank account.
