Hey...there's this comedian that used to work for this company...Universal Survey. Check out his blog (http://kidliam.blogspot.com/2006_09_01_kidliam_archive.html) and the Sept 21 or 22 entry on this...funny! AND I've suggested he turn our frustration into a Borat style Comedy Central deal to get this SOB's to stop calling!
OH, one more thing, my telcom said to call the FCC Complaint Division at 888-252-5322
and your state's Public Utilities Commission. They can make things unpleasant for Universal.
