They done a retest on me in 2019 I didn't write it down they didn't record it so they just cancelled my account my machine went out last night and I called them and they said they'd be here at 10 this morning nobody showed up nobody called nobody done nothing then when I call him they say my accounts inactive why didn't they called let me know something cuz they're lazy and inconsiderate then I called the home office and gave her the serial number off the machine I had and she said it wasn't one of their machines and it's got Lincare printed right on the front of it seems like they don't want to have no business they want to lose all their customers if I can find me another company around here I'm going to switch
