Red Roof Inn review: no water and charging me 75 dollars. for a accident that I couldn't clean

My wife and I stayed at the red roof inn at lookout mountain in chattanooga tennessee. I booked it on line. From nashville. So when we arrived she said the water was out. It late long drive and I like red roof inn. Some time in the middle of the night my wife had a accident from her treatments on the bed sheets. So we cleaned it up. And rolled the sheets up. So they can see them in the morning. So we left early to make my meeting. And they charged my card 75 dollors because they say we damaged are sheets. The manager was rude and wasn't trying to hear what we were saying. I told her if we had water I could have soak the sheets clean them myself but they didn't have any water. I will never stay at this red roof inn again. I feel like i've been ripped off
