No delivery and no repayment

I bought a product from groupon which i was suppose to have 2 weeks ago already after i had to be on the phone for 20 minutes with them. When called to ask again they said they have no stock so I can wait or cancel, this now after another 25 minutes on the phone. <br> I cancelled the purchase and still waiting to get notification that my purchase is cancelled and I still have to wait another 3-5 days I get my money back<br> This is extremely ridiculous as I have to struggle to get my money back which they had for 30 days now and earning interest on my money!! <br> I am extremely disappointed with the service
