I have had repeated calls from this number, and have dialed "1" several times to be removed from the call list, OR at other times dialing "1" is to transfer you to an operator ... neither works. If you do get an operator, they hang up on you as soon as you ask them to remove your number from their call list.
Heed the previous poster who said:
"he callers try to make you fall for a line saying they will lower interest rates on your credit card. They tell you to press 1 if you'd like your rates lowered, they then proceed to try to get all your credit card information without telling you what card or bank they are from. They claim to represent "All Visa and All MasterCards" When I called them on it and told them this is a scam, they immediately hang up. They have a computer calling out many people, and are searching for the few that will fall for the scam and blindly give them all their credit card information. Do not fall for this! "
