I've been working with Lincare for over a year now and they are the worst company ever! Just last night they called me with a "courtesy call" to see if I wanted to pay my bill. I'm doing the best I can and making, what is to my budget, a substantial payment each month. I was one day late and they were already calling me. When I told the woman that I didn't want to make a payment right then because I was driving, she hung up on me! Geez... I wish I had never gotten my CPAP machine from them.
