These people called my house twice. After reading the messages below I asked several hundred friends and colleagues to make one call each and ask for Sue and quiz her on the nature of her business, ownership of the company etc. I suggest everybody does this as well as complaining.
We are on the "no call" list yet received a call from this company. I called back and asked what their business is and was told that they are a third party collection agency. Also, they were asking for a person who does not reside at this number and who I don't even know. I have now used selective blocking and have blocked this number from our phone. (Caution - As these companies are unethical, they probably have dozens of other numbers though.)
