The staff was very stern and impatient and did not help me resolve my issue. I called to find out if I could get a mask fitted, and they fired back with at least ten reasons why I can't do that due to having purchased a CPAP machine somewhere else. The lady also went into a long explanation about how my insurance has "dug me into a deeper hole" and about how I should not have purchased my CPAP supplies from somewhere else. For the people working at Lincare Charleston, here's a little advice. When a customer calls, they don't want to hear about how they have a difficult and unsolvable problem, so next time, spare that. Focus on the solutions and what can be done to address the problems.
