No Service Whatsoever!

I placed 2 orders on the same day with GroupOn about 2 1/2 weeks ago. I used my PO BOX as a delivery <br> address and although the website accepted it I was emailed 2 days later to provide an alternate address <br> as PO Boxes are not allowed. I rep**** immediately with another address and received an automated reply. <br> That was as far as I got. A week later I emailed [Email Removed] requesting an update on my orders, I <br> was referred to [Email Removed] instead. There was no reply at all from this address. I resorted to the GroupOn website to track my order in which I also logged a query - no joy. I was also provided with another email [Email Removed] which was a waste of time, there was an apology from the US channel due to high volumes, etc. I find it really appalling that I have to make numerous requests to get information that should be provided to me. I have never had a single issue when shopping on other online retailers such as [URL Removed] even during the Christmas period. I tried logging on to GroupOn site today and it says my email does not exist and I should sign up for an account?! Definitely closing my account once my orders are delivered, if ever?!
