Samsung, where the hell is my rebate check?

Prize Logic are sort of criminals. Sent in rebate form via certified mail on October 24, 2014. Delivered to Prize Logic on October 28, 2014. Its now February 1, 2015 and still no money. Sent several emails. One meaningless response asking me for the same documents I sent them in my first email. So I contacted the US Post Office. Post Office contacted Prize Logic. They told the Post Office investigator they had already paid me and to call them. Three calls and no response. I think Samsung's financial problems are at issue too. Untimately, Samsung owes lots of us money and they are probably totally OK with Prize Logic's failure to pay. But its Samsung who's responsible and I will never buy another one of their phones. I did see several posts saying that a BBB complaint worked. I'm filing one now. Prize Logic is listed with the BBB and they've had a lot of prior complaints.

What contact info did you use to contact the USPS?
