These [***] call me all the time. I answered the phone this time, and politely asked to be removed from their list, and he said "no", I screamed into the phone, cursed, and that gave me some satisfaction!
After receiving repeated calls from this number for a very long time, today I answered and transferred to a live person. I immediately said, "Do not hang up on me." The man cut me off and said, "I'm going to hang up on you." I asked, "Why?" and he said he had to do so. I asked why and he simply repeated that he was going to hang up on me; that he had to do so. I have reported the number to the National Do Not Call people without result. As above, I suspect this is a Credit Card Scam.
