My physician's office placed an order through Lincare. After two weeks of hearing nothing, I called and left a message. No response. I called back after a week. They claimed they needed something else faxed from the physician. The physician's office said they never received anything and contacted Linacre. After another week, I still hadn't heard anything. I called a spoke to someone who was "looking into my case" That was three weeks ago and I still haven't heard anything. I ended up going with another company.
