Complaint Review: Tech Wildcatters

My company sponsored Tech Wildcatters (TW), a well recognized accelerator in Dallas Texas. We did a poor job of confirming the information provided by TW, and in hindsight, we should have had more meetings and verified TW's claims regarding their network, reputation, and ability to deliver on the sponsor agreement. At our first event, we had a disappointing turnout with less than 15% of the promised attendance. TW was unorganized and unprofessional. Fast forward a several months, TW forgot to use our logo as agreed to and no one contacted us after our information was provided in an email blitz to their network. Disappointed with the event turnout and now the failure of the email blitz, we attempted to contact TW on multiple occasions by phone and email. It was clear TW was avoiding us. We essentially wrote off the "partnership" until we received a series of emails accusing the CEO and her family of wrongdoing, theft, fraud and a laundry list of other crimes. The agreement was still active so we attempted to terminate the agreement, but TW never returned our calls or emails. We came across a complaint on BBB and on this web site. Clearly, we are not alone.  We would love to get our sponsorship refunded, but that appears to be highly unlikely. We are willing to discuss any options with any lawyers or consumer advocates.
