SHOCKING SERVICE - STILL AWAIT REFUND

I cancelled an order in Dec 2015 before it was delivered but the only response I received was saying that Groupon would contact me in 2 working days. But I never heard anything. I could never get through to them telephonically. So eventually the package was delivered which I then sent back immediately with the courier. <br> I got hold of Groupon after waiting on hold for about 45 minutes, and informed them that I had sent the package back with the courier. They advised that they had made a note on my account and would refund my money which they never did. Shana sent me an email saying they would refund me within 24 to 72 hours, this was on 12 Jan and I still did not receive the refund 5 days later. Then Shana emailed me to say she sees that the courier has delivered the package and hopes all is in order. I phoned in to say that she is extremely confused and that I sent back the package weeks ago which she had confirmed. Tanya has now cancelled the order AGAIN and said it will take 7 to 10 working days for the refund to go through. This is completely unacceptable. I cancelled this in Dec. I need this money refunded today.
