I worked for universal power marketing a few years back. they are a telemarketing company that sells a "shopping spree card". They work with companies and resturants in the town you live in, all around the us, and offer great deals, ex. 2 for 1's at different resturants, free oil changes, free rentals, etc..) and tons of free stuff, with this shopping spree card...
After a long pause a lady came on the line wanting to speak to the person that handles the long distance phone account. She claimed that she was with ATT and not a reseller. I did not beleive her and told her to have a nice day.
I called the number back and they answered as Mc Cullum Co.
