Under estimates clients intelligence

After my previous complaint a week ago. Your RM never called. I got a call from the manager that gave me a lot of information regarding what was tried and never worked or what they were waiting for to assist in the resolution the manager gave me the impression she only listened to me because he had no other choise...(I do not want to talk to her ever again). I was told that she will get back to me a day or two later as they were having a meeting regarding my complaint...she never called back and its now practically a week later. She had the audacity to ask me if it really was hot in the sauna or did it only feel hot after I saw the reading on the tempmeter. And since that day the thermometer has been removed and never brought back. I believe she thinks I am a child? I have used saunas long enough to know the temp now ranges between 85 and 94 degrees but leaning closer to 90. I do have to add that complaining was a waste of time with no resolution.
