27-May-2017: Received a robocall from "321-254-8977" wrt "LAST call for Lower Credit Card Interest Rates" so I pressed "1" to get more info to report on & to string them along. I got him to give me this number: "1-800-847-2911" WHICH is WELL addressed in all of these posts. I asked for & He said the name of the company was "Card Member Services" for Visa, Mastercard, etc. Spoke with an Indian male accent in a distant boiler room giving them bogus info, then got tired of it all & hung up. He (SAME GUY) called me BACK with a caller ID: "407-861-5698" wanting to know why I hung up, he tried to speak over me, from his script, while I told him what i REALLY thought of him & his biz & to ~roughly, take this as my LAST CALL!
