So i got a call from someone who offered me LEGEND credit card of IndusInd Bank with a fairly high limit as LTF. After that he asked me if i had credit cards of other banks. I told him that i had recently acquired an Axis bank credit card and so im not interested in applying for another one until 3 months else it will affect my CIBIL. He then told me that he can give me some SBI credit card saying that no other bank other than SBI will give me credit card until one year. Is it true? Or is it some kind of scam/fraud?
