Groupon - Avoid with all intent

I have been using groupon randomly since the inception of the service and on occasion have an issue but nothing worth reporting on. However the last transaction have been a FUBAR of note resulting that my family or I have will never use the Groupon Service again. I brought a product and when trying to track the delivery which was overdue the voucher just redirects me another page which states I must check my email.. When trying to call the call centre you are put in a queue and literally have to wait up to 20 minutes for someone to answer. I understand that Xmas is busy season but then staff up. After my spouse was told she cannot enquire on my behalf because the voucher was brought using my groupon account I called numerous times only to have the IVR tell me that they are experiencing high call volumes and that I should email them at which point the call is dropped. I also need to note that I had emailed Groupon as a first resort but with no avail. At this point I am hoping to either gt my products delivered or just have my money refunded. Worst service I have received in 2015. In my opinion Groupon should either improve its service or close it doors.
