Called twice on August 9th - no voicemail, and calling again today, August 12th, still no voicemail. I haven't answered yet, but if they call again I think I will.
I called back to the number and it is a company that says they will give you a $100 gas card if you join their discount/coupon group. They will send you the gas card and coupoons but they need to charge you $3.00 for shipping and handling which they will put on your Credit Card and could please give that to them over the phone... Riiight.
