Pretty sure this is a cold-calling/phishing scam to steal Credit Card numbers. Would not give me any information about who they were that shouldn't be a problem for any real company. Do not discuss anything with them in regards to your own cards.
i just got a call from them and told me that they will get my APR very low. by how much i asked, he said up to 0 % , right there i became suspicious, and later he asked me my credit card number and i told him i will run your phone number and your company name online and call you back.......guess what i found ....credit card scammers
