I wish I could give them a negative 10 stars. They are profiteers of the COVID sickness. November 13th I tested positive for COVID, I went to Doctors out side the Box and they were great. I needed oxygen for 1 day and the doctors wrote a prescription for it (they had to write it for 2 months for some reason but they said it could be cancelled with no charge). After about 2 weeks I had fully recovered. So I called Rotech to come and get the oxygen machine. They said that Doc's outside the Box would have to cancel. So I promptly called them and they faxed the order to cancel. I waited a few days and Rotech never got back to me. So I called again, they said they did not get the fax, so I called Doc's outside the Box, they faxed again. A couple of days still no answer, so I called Rotech again. Once again, they said they did not get it. So I called Doc's outside the Box and they called them, they told me it took 30 minutes to get them to cancel the order. The only problem was by that time Rotech was able to charge me another $133.00. If you need medical appliances tell your doctor not to get it from Rotech, they will rip you off.
