Credit Cards — Getting calls regarding credit card though we don't have the same

Address: 411028

Now a days, I am getting very frequent calls to check my credit card usage. When I ask which credit card you guys are talking about they do not give any answer.

Yesterday 09th November, 2015; I got a call from +91-[protected] and a lady was inquiring about my wife. When I said this is not her number and how did you get this number. She said they got this number from my wife's credit card profile. I was surprised because my wife doesn't have any credit card.

On asking which credit card you are referring to and questioning; she just disconnected the call and later I was not able to call that number back. This is now a days very frequent that we keep getting calls and looks all these are spam.
