I agree with all above,
But many times persons would like you to give them you credit card number over the telephone !
Even if you were of mind to give it, remember anyone can be listening over a scanner ! Anyone can receive your credit card numbers, name, address and phone number !!!!
NEVER give you information to anyone over an unsecured line ! And ALL regular lines are unsecured !!!
I have asked these idiots if their line was secure, and they always say YES !!!! THEY ARE NOT SECURE !
