No delivery and no one to speak to about it.

I placed an order and paid a considerable amount of money on the 19th January 2016. The automated confirmation email advised that delivery would be made in ten days.<br> I have tried calling Groupon only be told that due to high call volumes I should email them.<br> This I have done a number of times only to receive an automated response advising that due to high mail volumes there will be a delay in response and that I should phone Groupon directly.<br> Which I do only to be lead around the same cycle.<br> I have no idea what to do.<br> This is an absolute disgrace for a site that is so well supported.
