I too received a umsolicited card from SBI Card in addition to the one I already had. But I called the Customer care, send them a request that I don't need an additional card. Then I cut the card into 2 pieces and disposed it. 2 weeks later I received a letter from SBI Cards saying my additional card has been inactivated. Thus the problem was solved then. But still sometimes they pressurise me over the phone to acquire an additional card saying that I am thier prestigious customer. I safely declined thier requests.
