Cancelled order, no refund?

Par for the JD Group course. Abysmal customer service. Ordered a headset from the website. Waited 3 days and my item was "out for delivery". Then I suddenly recieved an email to say my item was signed for (by me) and delivered, except, nothing had been delivered and I did not sign for anything. After DAYS of trying to get hold of an actual human to talk to, I was told the order was cancelled due to incorrect pricing. Fine. Then I was told they needed to wait to recieve the headset back before they could process my refund. Why? You cancelled the order! Now it sits in limbo because the order shows "complete" on their system and they have my money and the headset now.

NEVER buying from these clowns again! That includes all JDGroup companies.
