Cashforiphones.com Cashforiphones ripped me off!!!!! Sparks Nevada

Cashforiphones.com ripped me off. I was quoted $207 for my iphone 5 in excellent condition and after they got my phone they tried to give me $16 which I did not accepted. I told them thAT same day that they sent me the email stating that they were going to give me $16 dollars for my phone after quoting me $207 that I didnt not want the $16 and to give me my phone back. I never received and email response. I called like 12 times, getting cut off every time and I also emailed them like 6 times. I just want my phone back or they money they quoted. I cant not stand when people rip hardworking people off. I am reporting them to the BBB and trying to get a class action suite on them.
