Paytm — Paytm fraud through call

Address:

Chennai, Tamil Nadu

Hi, I have recharged in paytm to my mobile, unknowingly I have recharged to wrong mobile number, so i have raised a request to paytm. Today I got a call, he said that, I am calling from paytm, he asked all the details about the recharge and he asked the card details, and cheated to 10000 rupees. I have the call recording as a proof. Kindly think about this point. 1) How he got my confidential recharge details to outer person? 2) After raising the request, with in 6 hrs I got call.
