I called Lincare on Friday 12/13/2024 and told them my regulator was leaking oxygen in my carry around tank and all they did is replaced the small gasket I told them it wasn't the gasket. Called again today to inform them it was leaking around the gauge and they said I have to wait until Monday. I can't even leave home being afraid of running out of oxygen. They don't care about the well being of the patients as long as they get paid!
