I'm sorry that Bennett Medical seems like the only show in town for BiPap supplies. The robocall system didn't work. The direct line only got me a "we'll call you back" promise, and that was the one time I was lucky enough to get to a human being. Otherwise, I called several times on each of the direct and general lines, and got the recording every time. Thankfully, I only need filters, so I'm going to order them online where you can actually get some service. If I didn't know better, I'd think this was a government agency.
