What this is scam telemarketers calling from a boiler room with a spoofed or stolen phone number. Very common these days. The caller is a crook so there is no reason to pick up or deal with them.
Tricked me into answering , turns out to be that dead blame Rachel from credit card services. These people will stop at no lengths to get live phone numbers. I hope & prey that the fleas from a thousand camels infest their body hair & make them the kind of fleas that you can not kill. These people need to get a life.
