I have been caught in a loop between my physician's office and these so called Suppliers! I have had documented proof that they have received faxes for a new RX from my doc. They give me the run around every time I chat or call. "We are still waiting on a response from your doctor." So despite actual telephone conversations with the office staff and multiple confirmations of the correct PH # and FAX# to use. Still 6 weeks out and I still do not have a critical piece of equipment! SO, I am going to tell you this. I WILL NEVER RECOMMEND THIS BUSINESS. They give absolutely NO F*CKS for the patient. If I could give them a ZERO they definitely earned it. Go somewhere else if at all possible.
