Oh yes dear, you DID sell me an oxygen concentrator that DIED and you told me to send it to another state other than yours to repair it. The repairman said he could not fix it and then told me I had to pay to ship it back to me. You are A LIAR AND A GREEDY POS. I WILL POST THIS REVIEW EVERYWHERE AND PEOPLE WILL KNOW NOT TO BUY FROM YOU. HORRIBLE HORRIBLE CUSTOMER SERVICE AND RUDE PEOPLE. GREEDY POS.
