Paytm Mobile Solutions — getwoo deducted 900/- without asking authorization

I have received the R's. 900 deducted d message on my mobile and seen the details that Getwoo deducted 900 today without my knowledge and without asking authorization.
This is completely not acceptable at all, How someone directly deducting the amount from my paytm...
What is the security of my money?
That has to be come back to my paytm account.
