Super 8 Motels Whites Creek TN I went to take a hot bath and the bath mat came up and the tub was covered in black mold White Creek, Tennessee

I stay at Super 8 motels all the time, I have MS so I need to take hot baths before I go to bed to help with pain. At the Super 8 in Whites Creek TN I had went in to take a bath and was running the water and  part of the bath mat came up and under it it was full of black mold. I took pictures and you can clearly see the glue residue and all the black mold. I contacted the front desk and they could not send anyone down or change my room, they would not give me a discount on the room and when I talked to the manager he accussed me of pulling the mat up and said that it was the glue that was black and that there was no mold.
