Still no delivery, shocking service

I ordered a TV on Groupon on the 27th April and I have still yet to receive the item. Delivery was promised for 14 working days, it is now on 20 working days and still no delivery. I've called the call centre on numerous occasions, everytime they promise to get back to me and no one ever does. No one can give me proper information and everything is just vague. Am I ever going to receive this TV?<br> <br> And lastly, please change the information on your website about your call centre operating hours. most days the call centre is closed from 3pm. <br> <br> Groupon Code: ***V0Q<br> Security Code: 16586AA56F
