In this number you will hear a recorded message about receiving a retail voucher of $100 for a small fee which is about $2 and 90 something cents.
I checked and they only accept credit cards, you can't mail them the money or anything else.
You can hear chatter in the background and the people who answer have a foreign accent.
I believe that this number may do multiple scams as half of the time you get the recorded message with the retail voucher and other times you don't get that recorded message.
This number is not active after 2:00 PM central time as it is after there "business" hours.
This number is 424-488-0548.
