Give them FAKE numbers next time.  :))

You must *NEVER*NEVER*NEVER* give out info to STRANGERS who call you.

same number , credit card discount , credit card holder promises rates reductions
2x i,ve asked for names and locations , credentials , they couldnt respond with any information
they need to be prosecuted , they seem to be on a fishing information , reconnaisance
asked for all my card data , fraud , lets go after them count me in

This company is a SCAM!
When I noticed they were asking for too much personal information I hung up.
They called me back from 404-392-0591.
They asked me if I googled the number (VERY SUSUPICIOUS)
When I asked for company name, address, office location they changed the story and said they
were based out of Atlanta Ga:
Account Service
License #M22232
When they gave me the Atlanta, address- it was Stone Mountain, GA with a 542...zip code which is NOT GA.
Then the caller hung up on me.
This just proves NEVER give your credit card information out to "telemarketers" that call you!!!
