POOR SERVICE-NO REFUND!!

I placed an order for ONE shoerack on Groupon on Thursday. The order was duplicated and my account debited twice. There was also a special for two shoe racks. If I wanted 2 , I would have ordered 2. I called immediately on Thursday to sort it out before the order could be given to the courier company. Tasneem assured me this will be sorted and a refund will be processed to my Credit card. I did this to ensure 2 shoe racks were not going to be delivered. I then get an email to say my case was not solved as yet. So I called the call centre today. The lines were extremely bad. The call centre agent tells me if two shoe racks come, I must not accept one. Low and behold, 2 shoe racks arrive this afternoon. When I refuse to accept one, I was told that they are just the courier company and I have to take both and then call them again to come fetch one. This is highly annoying as I have always purchased vouchers from groupon. This is my first goods purchase and the service is terrible.
