"Kim" called my cell phone asking me to call her back at the office number with an extension of 206. 'Very Important.' Well aren't you supposed to identify who you are calling with? If not, I dont think many people are going to call you back.
My boyfriend called me at work stating some MARCO called and left his ext. 211 and a reference # for me to call back. Just like electra28, I don't owe any bills, so I immediately googled the number and here I type after reading all the other posts. Scam indeed!!
