I ordered a oxygen unit a year ago March, that is 2017. I am still waiting. They always have some excuse. Lying is easy for them. Kim told me October 2017 she had ordered one for me. It has taken so long the required tests are obsolete and needed to be repeated. I don't know how this place stays in business. I emailed Corporate and they must be immune to complaints by now as i did not receive a response. Carol Wahl
