I would give them a zero if that was an option. I sent my daughter-in-law to have my tanks filled on this past Tuesday the 5th and they opened at 8:30am. My daughter-in-law was told she had to call before she could have them filled but they did fill them but the girl Roxanne continued to berate her for not calling in first which we were not aware of. No one helped her with getting the tanks in to have them filled. They did however help her get the filled tanks to her car. When I find another oxygen company I will drop them like a hot potato. Tired of them not being able to help a customer when they need help. Have had many problems with this particular Lincare.
