Oxygen Cylinder Delivery

Vitalaire is the worse service provider. I logged a request from the 22nd till today no Oxygen received. Everytime I call in they always say today. They mentioned that they are running short of cylinder bottles they will come around to collect the cylinder to refill and bring it back even today we are still waiting. When you ask the ladies that work there about the turn around time they don't know. The bottles they bring are always almost empty and last a day only.
