This is a scam to get $399 don't call back

I posted my home for sale on craigslist and got a call from this company saying they were DC By Owner and a woman named Estella gathered info about my condo and they was going to transfer me to her "Supervisor".  I stated that if this was asking for money I was not interested, she proceeded to transfer me, but instead chose to hang up.  Be mindful to ask questions before giving out too much information.  I have asked to be removed from their phone contact list and we shall see what happens

I received a similar call and was transferred to his supervisor when I asked him questions.  The first one was trying to "screen" the calls for the closer!  When his "supervisor" came on the line, he had the hard sell spiel that I hate!  I tried to ask questions, but he interrupted me every time.  I got a little upset with this and told him that IF he was going to be rude and NOT answer my questions I was not going to listen to him any longer.  He told me that I should speak to someone else since I did not like his way of doing business.  I told him goodbye.  They lead you to believe that they are calling to purchase the house you have listed at Zillow.com, so this is a pain!  I am on a Do Not Call List, so I guess I need to file a complaint now that I have read that it wasn't just me feeling that way about them.  

When it sounds like a duck, looks like a duck and waddles like a duck, it probably is a duck!  SCAM ALERT FOR SURE.
