Horrible service from this company that supplies oxygen and supplies to the medically fragile population. Been trying to get a repaired or replaced portable oxygen concentrator for my mother for over a month. When you can finally get someone on the phone they conveniently "lose the call" or give you a totally different story about what the status is. Their corporate office is ridiculous as well. Very hard to reach including their billing office. I have been hung up on 3 times this week while "holding" for them to try to get answers. DO NOT USE THIS COMPANY!!!! read more
