Well they finally thrown the towel, and starting telling bs,
It's quite easy to refund by the aliexpress system, why they want to use PayPal, after a 5 start positive, It's another dodgy behavior.
I will fight to help them learn to be honest, and work with honest behavior, not a dodgy seller creating lies, like quality problems, or lost in the parcel, things that do not happen without at least the tracking be running.
The fact they have the stock, they are greed, and they creating excuses, to try to sell at a higher price, The honest behaviour was ok, I made a mistake on price and the order was cancelled , here is your money back, Everthing prior to shipping.
