Lack of communication and poor response

Good Day<br> I bought a pressure cooker from Groupon on the 27th November, I was told that the tracking number of my product will be sent through to me, it the 10th of November I haven't receive anything, I emailed them a week ago but I haven't got any feedback regarding my order, I have been trying to contacting them.<br> their call Centre is always experiencing high call volumes, one will hold from being caller 96, which is to hold more than an hour, when you get through they tell you that their system is off line they are not able to assist, after waiting for an hour, I need to know the status of my parcel.
