LATE DELIVERY

I placed an order for a Telefunken television on Groupon on 9 January 2016 and on the order it specifically states that delivery will be within 10 working days. As today is the 10th day, I phoned them to find out if the item will definitely be delivered today just to be told that it has not even been dispatched yet. The gentleman I spoke to could not tell me why there is a delay and said he'd have to refer it to another department and it would take approximately tow working days for a reply. He also told me that they cannot accept responsibility for shipments as that is the responsibility of the merchant. Surely if Groupon advertises a product they have to take responsibility.
