Groupon Deal Gone South!

I ordered a deal for Printstagram from Groupon. <br> <br> On making the payment I made an error with the customer reference code. On calling Groupon to inform them of my error and request assistance with it, I was informed that they had no way of tracking the payment (so HOW do they credit it ?) and that I had to make the payment again. So I made the payment again with the correct code. <br> Now the deal has disappeared from My Groupons and Groupon has R200 of my money with nothing to show for it. <br> <br> They are not replying to any attempts to contact them, and quite frankly I'm not throwing more money down the drain attempting to call them again and holding for nearly half an hour (R60 later on my cell).<br> <br> The deal MUST be finalised by the 13th and it was a very special Christmas gift. I want them to refund me the one payment and process the other. IMMEDIATELY! <br>
