They only provide you with small amount of tanks for month plus if you need any other equipment they do not provide immediately they do not even answer the phone calls orders even when you leave messages. They are really bad on answering questions or trying to help you is not possible for them they just do what they please. I have already more than a month trying to get a hold of them and they do not answer at all. Now am despret to have my oxygen tanks so am gonna have 2 drive all the way to their offices and see if they can help me and give me tanks their. I have a collection of empty tanks in my living room just waiting and taking up space. So please listen to me this company is the worst I retreat being hear I am just waiting for new orders to get out of this company but mean while I have to deal with their rudeness and they not answering.
