NEVER AGAIN WILL I BUY FROM GROUPON

My order for 6 Trestle White Folding Tables were placed and paid for via Credit Card at R 599 each - last year on 2014/09/17. Since the placing of the order only FOUR tables were delivered. I have been mailing GROUPON Support since then on various occasions and had NO response. SIX emails were sent (2014/09/26 - 2014/10/28 - 2014/11/12 - 2014/11/19 - 2015/02/06 - 2015/02/12) and nobody had the decency to call me back to say they will refund me or they are busy to follow up on where exactly the two tables disappeared to. <br> In my opinion this service is dreadful and unacceptable and I demand that the money paid for the two tables not delivered will be refunded back to me.
