Lincare Holdings review: Nebulizer

Lincare provided respiratory equipment to my home after surgery. In addition to the portable oxygen equipment they sent a nebulizer machine which was sold to me not rented. On delivery ofit I told the delivery person to remove it as I already owned one. He said he'd put in the order for removal. It was not done. Subsequently when invoices arrived I reiterated the issue with the nebulizer and was told a credit would be issued. The rented equipment was all returned after 5 or 6 weeks use and the nebulizer--unused- was then returned as well. As i have the receipt showing it, that they acknowledge. Nevertheless, Lincare continues to bill me, their customer service and billing people ignore numerous letters and attempts to converse by talking rudely over me and repeating "we don't prorate". I and my insurance company have paid for the services received but I do not believe anyone should be paid for an item that was "sold" that was not used and returned.
