I have documentation of abuse by the manager as I've saved every bit of communication between him and myself. I have pictures of mold and mice problems. I also have pictures of evidence of lying to customers as even at the time I felt these to be wrong. This business is not in the DFW area but a majority of our clients ere from that area. I am just questioning the legality.
