Apria Healthcare Group – Inability to fill an order completely, various excuses given including item not covered

Every three months I order my cpap supplies. Each time I am told what is covered and what will be included. Since COVID I've been ordering 2 extra items, (diffusers) which are covered by my medical plan (Medicare & supplement). When received the actual order varies. Sometimes the 2 diffusers are included, others they are cut in half or totally missing. Each time Apria gives a different reason. Either they are not covered, only allowed to order 1 and when I request it to be filled, they don't even place the order.

When I attempt to reach their corp office to complaint, all their numbers listed route to the same customer service center. I even reach their main call center which could not provide a number to call that didn't route to the same customer service center. Even their corp number routes there.

I am to the point of changing my supplier, maybe I can get a complete order with one phone call.
