Paid Lisa Blackman $1, 500 to co sponsor an event that was to be held at House of Blues in Chicago in October 2011. As part of the agreement which was in writing, my company was to receive a full page free ad in SU Magazine. The $1, 500 was paid 9 months prior to the event. Shortly before the event, Lisa Blackman said she would not honor the agreement and refused to refund the money
