The San Louis Obispo California lincare was some of the most uncaring rude people. They were notified in advance about my travel arrangements. I tried to explain to them i couldn’t give them an exact ETA because of traveling by car and stoping to rest along the way . I called them several times and spoke to the same woman at least twice letting them know where I was and let them know I would arrive on Tuesday. Unfortunately I did not get the people in the office name I spoke to. The person told me it would be no problem to exchange my empty tanks for full ones so I could make it to my next stop on my trip . When I arrived they made out like I was a lier and had never spoken to them . I have stage 4 COPD and they couldn’t care less if I had oxygen or not . Stated they had a shortage in tanks they would not exchange tanks with me because they would not let the individuals on their route go without tanks . So what would I do without o oxygen tanks ??? They didn’t care They told me they could not help me . Luckily there was a great professional office in Bakersfield CA 2.3 hours away that helped me with no issues. This caused me to lose 5 hours of visiting time with my daughter that I may not see for a long time . Shame on you San Louis Obispo lincare .
