They called, they left no message, I called them back and that's when they made the big mistake.  The answering system said " Congratulations, for visiting one of our online sites you have won a free gift, please press one to claim your prize."  In their system like so many it probably has programmed that if you pressed one, it gives them the right to see your phone number, or something like that.  In my day, we didn't have to take advantage of the customer - for any reason, we gave quality at a reasonable rate - not so today.  They are out to get you.
The caller identification gave a read out of: " WAMART"  NOT - "Walmart".
