This company called claiming to offer debt assistance. The same recording they used has been used for a couple of other scam calls made from the Washington state area, and this number comes up as from Renton, WA. As per whatever messed up policy they have, I couldn't get a REAL company name, instead was hung up on. Called back and put myself on their do not call list, but it seems like this company is simply rotating through numbers and hitting me up on different ones within 48 hours of being put on their list.
BTW...a google search for NSI came up with a real estate company in Michigan. *shrug*
