The chair I received had a defect in the side bracket that supports the back part of the chair. I email you guys and was advised that a new chair would be sent out. Then I received an email from your customer Services asking for pictures so I sent out pictures showing the defect and I was advised that I would receive a refund. Now no work on how this issue will be handled. At this point I'm very disappointed at your customer service. I use the chair for work and now I'm having back problems from the chair I'm using now.
