Complaint Review: Quick Laptop Cash

This company offers to buy back used laptops, including broken laptops, for cash that can be paid via check or Paypal.  My laptop is a Dell Vostro V13, which is quoted $180 on their website for buyback.  My laptop has a broken keyboard, so the quoted price went down to $144, which I agreed with, and I shipped my laptop to them.  A week later, after they received my laptop, they emailed me back saying all sorts of things like:  "Your laptop has a bad keyboard and bad battery as well as a broken screen. This changes your order total to $38"!  I'm pretty sure that my laptop does not have a broken screen or a bad battery.  Everything was working fine except a broken keyboard.  

In fact, I decided to sell it after 2 years of using it ONLY because of a broken keyboard.  I told them it had a "broken keyboard" before I sent the laptop out to them, too, so it's not like it was new to them.  The quoted value was $144.  And YET they invented all sorts of things to pay me only 26% of the promised price!  This is FRAUD!  I emailed them back saying that if they claimed my laptop had a broken screen then they should show me pictures of where the broken screen is, and they NEVER reply me, or in other words, they could not prove that my laptop was broken!  The next day, I emailed asking if they could return my laptop, and they play silence for a week without getting back to me!  

Finally, only when I told them that if they didn't reply to me, I would report to the police, they replied me very fast saying that they would return my laptop IF I pay them $35!  Why should I pay $35 for nothing and even if later I decide to sell my laptop to someone else, losing $35 to QuickLaptopCash would devalue the profit I'd get from next-time sale. Plus, I knew that if I did not agree to their rip-off deal, they would keep/hold my laptop for another long time (weeks) of silence - in other words, they would never return the laptop to me!  Dealing with them was very stressful enough - they intentionally make the process stressful so that they could have a leverage over you and force you to accept their rip-off deal:  

They claimed your laptop was broken but could not even provide evidence to prove it!  And if you don't agree to basically give your laptop to them for rip-off price, they will play the silent game with the intention to keep your laptop forever; if you don't warn them that you will report them to the police, they would literally steal your laptop!  This is professional con-artist!  This is not even a "company" - it seems like there's only one person running the "company".  Furthermore, the person communicating withme was extremely rude, and they never picked up their phone!  Even if they returned my laptop, I would not trust that they would return my laptop in its original condition, either. This business should NOT be allowed to deceive people out there any more!
