Murray Hill National Will recruit you for a study but not pay you Dallas Texas

I have had 2 bad experiences with this company. The first one I was recruited for a study for a sister company of theirs (or so they said) here locally but when I arrived for the study they had no record of me. No pay, no return call. 

I was contacted in early July about a Pepperidge Farm bread study. I made several videos, had them uploaded, spent time on the phone both with the organizer and with the client. I was promised $200 for the study but have not received my payment and have tried contacting the company several times. Nobody ever returns my call.
