This is the worst place to do business with. Last week sat on hold for over an hour and now today 8/10 same thing. I think they may have 2 people answering phones.
Also they do not read instructions carefully and the reason I say that is 2x now my doctor has told them, by letter, that I need oxygen 24/7 and they send bills to medicare OXYGEN NOT NEEDED.
GO ELSWHERE!
