Sellandrecycle.com Took my cell phone and never paid me. Chula Vista CA

SellandRecycle.com buys old cell phones. You mail the phone to them in an envelope that they provide. When they get it they tell you the value. Then they are supposed to send a PayPal payment to the account you provide. I did everything as they said and heard nothing in the time frame they describe. So I emailed them. They said it takes a few days. Then they said my $40 was approved. I never got it and emailed them again. they said it was paid to the wrong account and they would take care of it. I never got paid. I emailed again and they said they were contacting "our merchant" to find out why I have not been paid. Nothing. I have called three times and you get put on hold for about twenty minutes. Then then come on and say everyone is busy and to leave a message. No return calls. Nothing. I have emailed the four more times. Nothing. Never paid me! They have my phone.
