Unacceptable consumer practices!!!!

<p>i purchased a patio set in November 2015, these things dont come cheap so i did my homework beforehand to ensure that the product would be suitable for our climate, which by all accounts, it was. I received the item in December 2015, in a flatpack, ready for assembly. Once the holidays started we assembled the set, as per the instructions. Imagine my disgust when, in June 2016, i find that the coffee table had totally disintegrated!! after contacting groupon to find out about getting it replaced, i was told that the warranty had expired 12 days before i reported the matter. 12 DAYS!!!!! Now i am told that the supplier no longer stocks that specific item. I have not been offered a replacement, an alternative option and groupon will not refund me either. Is this acceptable consumer practice? </p>
