Lincare home care supplies, cpap. oygen concentrator New London Connecticut

I have been out of the hospital for a week after suffering a heart attack and being in a coma for most of the month of June. A CPAP machine was ordered through Lncare for my home along with an oxygen concentrator. The machines were delivered, but no mask! i have made numerous calls. and was finally told that a mask would be delivered between 4 and 5 pm today. I called  again at 5:45 when no one arrived with a respirator mask, and was told that a manager would call me. They told me the maskmight have been sent through UPS,but they weren't sure. I waited until 6:30, and received no return call from them. It is now 6:44pm. their office is closed. and I was told by their answering service that I should "maybe call back Monday". I am so very upset about this, as I have had interrupted sleep since arriving home 7 days ago. It has now been a full week since these people were assigned to my case. What a farce! Lincare office in New London Ct is very poor when it comes to customer care. How do these people keep their jobs? Now it is Friday evening and they, unlike me, can sleep over the weekend. They are billing Medicade for this machine even though I can not use it due to their ineptitude and poor follow-through in getting me a face mask to use with it. What happened to customer service? it sure does not exist at Lincare, because it seems that Lin-doesn't-care at all.
