Asking if I wanted to reduce the interest rate on my Visa/MasterCard. He had no details on the credit card he was calling me about (when I asked he said your "Visa/MasterCard....umm now it is either one or the other). He was calling with Indian accent and I asked why he was calling me on this particular phone line about my credit card (I know I do not use that phone # for that card)....told him to remove me from their mailing list. He hung up on me. I believe this to be a scam.
