Worst Return experience - NO REFUND!

Dyson's customer service and processes are the worst. I ordered the Airwrap and returned it with in the given time frame since I didn't like it.
First when they sent me an email with return label information, the email did not contain the return label so I had to call them wait on the call for hours together. Finally i got the label and sent the device back. I waited for a few weeks and still did not get refunded. So I called. The first 3 times I called I've been told - it takes  long time for the refund because of the holidays and the amount of orders they have. 
Fourth time I called they told me they did not get the device from UPS after making me wait on the phone for atleast 2 hours with multiple people. 
After speaking to a very rude supervisor, she raised a claim with UPS on my request. I had to call UPS to get info on the claim. UPS told me they sent all the proof that they need about the claim. But dyson kept me waiting still. They said 72 hours first, then they said another 48, and then 8-10 business days. 
Nobody has answers to anything. Since I returned the device and UPS confirms they received it from me. From here on, it should be b/w UPS and Dyson. I don't understand why I'm being kept on hold for my money. 
The most unrealiable customer service ever. Never buying anything from this company again.
