The callers are the drug-addicted "card services" scammers, who call us, pretending to be associated with our credit card companies, in an attempt to fool us into giving them our credit card numbers, so they can rip us off. People that have given their card numbers to these junkies have suffered severe financial losses. Beware of these lowlifes, and warn others, before they are cheated!
Had some fun with them. Looked up 'credit card test numbers' to get a fake number that will some up as valid for the scammer. I acted ignorant and made them explain things to me multiple times. The number I gave them apparently came up as a bank card from Columbia! haha When I gave it to them they said it was to verify it. I asked it it was correct - they said it was the same # they had on file. haha Then they asked for the last 4 digits of my SSN. I could have given them another made up # but instead told them I was afraid to give them that info and I would feel better if I called them. They said since it was only the last 4 digits of my SSN, no harm.. right? I told him that all any bank ever requires is the last 4 digits of a SSN so it's as good as gold. Then I broke it to them (His boss was on the line at this point) that the CC# was a fake and I was on to them. It took a while for it to sink in. Wasted their time and since I was waiting on another call... no waste for me.
