We just received a call from this number and the woman on the other end was asking for my wife. I asked who she was asking for again and she said (in thick Indian/Pakistani accent) "Yes xxxxxxx, We have access to your credit card payment history for the past 6 months and see that you're paying 6% over average".
I asked her where her company was located .......
(sounds of her turning to someone in a place with alot of background noise followed by her saying...) "wha?? (followed by more non-english inquisitives) .........and then she hung up.
