Definitely a scam. They say they’re from Visa and want to reward you with free gift cards. They had my address and the last four digits of an old credit card. When I told them that that card had been canceled due to fraudulent activity, they hung up on me.
This # has been calling my house for about 2 weeks...every day. They always call during the am when no one is home & they never leave a msg. When I called the number back the first time, I got their voice mail and was able to leave a kind message to remove my number. Today I called and wanted to raise.... their mailbox was full. Go figure. My # is unlisted and on the DNC list. WTF?? If they'd just call after 5, someone would tell them where to go!
