I don't know how a business can conduct themselves in such a condescending manner. After my personal experience, I've shared with many how awful it is they ship used items with missing parts and then treat the customer like an idiot.
I deeply encourage everyone to shop elsewhere. Don't waste your money (you'll just receive defective products with an attitude when you report the defect and/or the return of a product).
Overall, my experience is well on its way to a fraudulent experience.
