I am a North Carolina Interior Design / Food Service Design Company that has been engaged by a Georgia Architectural firm to do an Interior Design / Food Service package. A written / signed approval was issued by this company to mine. The work was urgently required & we spent many months and much overtime to get them an 80% set of Revit Design Development Drawings. Our invoice is now more than 7 months overdue. Initially we got the run around, but now we are being ignored.
