Returns or claims for reimbursement shouldn't be that complicated.
By comparison. I bought a Drone flight controller from CNCHelicopter last Friday - the owner called my cell phone 5 minutes after I placed the order (to confirm shipping address was to a hotel)
I also paid for fast shipping - it arrived Saturday afternoon.
Unfortunately the GPS was faulty, I emailed CNC, received a reply within minutes telling me to ship back the GPS and provide a tracking number.
I posted it Sunday and sent tracking info to them - Monday morning they shipped me a new GPS which should arrive tomorrow.
THAT is the way to do customer service. Good Job CNC Helicopter!
