This is good, take brand new unit of others and give them a refurbished one. That's all i want is either give me a fresh unit or give me back my faulty one i dont want this dirty refurbished unit against my brand new unit

There executive saying that you will receive a fresh unit but provided me a dirty piece of [censored] this is disgusting

Hope immediate action will be taken
