Don't trust URS for anything. They are bottom feeders. They use abusive language and will harass you at every turn.
Since January of 2009 they have had 26 lawsuits filed against them. Since August 2008 that number jumps up to 38 lawsuits filed against them. Most of these lawsuits are for violations of the Fair Debt Collection Practices Act. Then in 2004 they were fined $240,000 for violations of the Fair Debt Collection Practices Act. This company uses illegal tactics to collect a debt, they don't care about our rights.
My advice send a Cease and Desist letter now. And when they violate that sue them. You can get up to $1000 for every violation.
