Claimed to be calling for Visa, Mastercard and Discover card.  I could hear a whole bunch of foreign accents in the background so I proceeded with my "security check" questions:
I asked where they were calling from, the woman with the foreign accent said "Orlando"
When I asked her to verify the zip code of Orlando Florida she hung up.
Works every time, scammers don't even take the time to back up their stories.  When I tried to call them back, it went to a "if you'd like to be put on the do not call list" recording.

Has called twice this month (December) and left no message.  Location is Alabama, and the ID caller reads Survey. I don't do surveys.

answered the call said hello twice then a woman came on said yes (a lot of office noise in back ground) then phone went dead

Spam call. Blocked this number off my phone.
Beware of this phone number. It's a scam call.

Female caller called on February 10, 2015 at 11:48 a.m.

She called about credit cards, specifically about Visa/Mastercard.

She wanted to know what our debt on the credit carda were.

My husband told her "zero" and she hung up.

We have tried telling these UNWANTED callers that we are the NO CALL list.

They are a nuisance, annoying, unwanted and I can't see why they aren't stopped.

They call from various numbers and locations.
