DGGirly,
My sorority sister, maybe you should consult a lawyer, but in any case, I would break my contract with that company! It sounds like they are failing to provide satisfactory service. You should definitely make a detailed list of everything that they have done wrong (including putting a Senior with New Members), as this will serve as ammunition. I would ask the lawyers on this board what you can do: lauradav and valkyrie and there are surely a few others!
You should not be putting up with that nonsense!
