WRONG DELIVERY, AND STILL NO DELIVERY.

I AM VERY DISAPPOINTED IN THE SERVICE I RECEIVED FROM GROUPON THESE LAST ALMOST 2 MONTHS. I PLACED A DELIVERY FOR A 3 PIECE LUGGAGE SET ON THE 08/12/2015, THE PAYMENT WAS CONFIRMED THE SAME DAY BY GROUPON. 10 DAYS LATER (18/12/2015) I RECEIVED A DELIVERY ( AT THE WRONG ADDRESS) AND THE DELIVERY WAS A CAMPING CHAIR?? NOT EVEN CLOSE TO MY ORDER. I KNOW MISTAKES DO ACCRUE AND I SEND IT BACK AND CONTACTED THEM MONDAY 21/12/2015. ONLY RECEIVE EMAILS BACK STATING - THEY HAVE A HIGH VOLUME OF EMAILS THEY WILL GET BACK TO ME ASAP. NOTHING FURTHER. THE FIRST WEEK IN THE NEW YEAR I EMAILED AGAIN, RECEIVED THE SAME EMAIL A FEW DAYS LATER. I'VED LOGGED A TELEPHONIC COMPLAINT AS WELL ON THE 06/01/2016- WITH THE RESPONSE THEY WILL GET BACK TO ME WITHIN 72 HOURS, WHICH AGAIN I ONLY RECEIVED AN EMAIL , THEY WILL GET BACK TO ME. AT FIRST I WAS NOT ANGRY WITH THE WRONG DELIVERY EVEN THOUGH I WANTED TO USE THOSE LUGGAGE SET OVER THE FESTIVE SEASON TO GO ON HOLIDAY - BUT ITS A MONTH AND A HALF LATER AND I HAVE NO IDEA WHERE THE LUGGAGE SET IS AND IF I AM EVEN GOING TO GET MY 3 PIECE LUGGAGE SET??
