It is hardly a scam if it is so easy to get a refund.
Shame you do not appear to have used the correct way to get a refund, (opening a NOT RECEIVED case) as that would then reflect in the trading history of the Company, coupled with negative feedback.
For buyers who are foolish enough to do nothing within 30 days, they will not get a refund, but can ask their payment provider for help. If paying by Paypal the rules are the same as ebay 30 days.
