Cash for Laptops Lied about communication, stole phone. Recorded conversation, unauthorized. Sparks Nevada

Offered $143 for IPhone 4s 16g.  Phone was barely used and in new condition.  Went on website, registered and they sent me a box.  I entered my email address.  The website said they would send me an email when they received my phone and they another with a real estimate once they inspected it.  Since it was in brand new condition I assumed it would be approx. $143, maybe $130.  I got the first email and waited for the 2nd.  When I did not get the estimate I called them and was told they tried to PayPal me $10.  

They did not have my PayPal ID!  They told me the phone was damaged by water.  NO WAY!!  I reset this phone before I sent it out.  It was perfect.  I asked for the phone back and was told it was too late.  The offered an additional $20.  I refused and was told I had no choice.  the said the sent out the estimate email and the fact I didn't get it was not their problem.  I asked for them to forward the email to me so I can see it and they refused.  "Take the $30 or nothing!"  

I asked to speak to a supervisor and was told that was impossible.  They are very good at this!!  When I realized I had no recourse, I agreed to the $30 after 20 minutes of a heated argument.  Melanie, the very well trained scamster, said "this call had been recorded and you agreed."

Nevada is a dual consent State.  The cannot record me without notifying me and me consenting.  This is a scam and a ripoff business.  Stay clear.  I will continue to tell this story till they are out of business.
