I also have this number for Sleep Circle. Extremely difficult to get in touch with anyone in authority. Generally all one can do is leave a message. This company is now owned my Linde, a German company providing medical gases and equipment. Lincare, Linde's medical equipment company, purchased Sleep Circle in mid 2015.
