Paytm Mobile Solutions — Reward points call - paytm - same amount debited 4 times

Address: 421201

Hi,
I have received a call regarding reward points. Due to which rs. 9850 was debited from my account to keep the amount for security. But after debiting rs. 9850 once, the same amount around 9000 was debited three times again. Twice the message says info vin*pay and debited amount is 9850 and another twice it says iin*paytm in which once 9846 is debited and second time, 9600 is debited.
Please help.
