Shocking service

I ordered goods from Groupon on the 29th October. It is now the 20th of November and I've not heard a thing from them. If the courier company hadn't contacted me I would still be unaware of the fact that my order was dispatched on the 16th. Here's the thing, although I've used Groupon before, and they have my correct address, they've dispatched my parcel to another province!! When I contacted Groupon to have them rectify the situation all they would do is give the the name of the courier and tell me to contact them. They wouldn't even tell me who I'd actually bought the goods from. And they are not interested in getting the parcel delivered. Surely it's the responsibility of the company I purchased the goods from to see that I get the goods when I'd given them the correct address in the first place? And when I try to speak to the CEO I'm stonewalled. On top of which every time I phone in I have to hold because I'm number 6/7/8 in the queue! Shockingl service!
