NO VOUCHER CODES, PATHETIC ASSISTANCE!

I have ordered 14 Canvas prints from Groupon, 2 weeks ago.... ( over R 2000) <br> Received voucher codes that was not valid and could not place the order with the merchant.<br> I have been making calls daily between Groupon and Prinstagram trying to have the matter resolved. <br> Each time I am told they will get back to me, and they just dont.<br> At one point I was holding on over an hour for groupon.... horrible service.<br> <br> Finally after a week and a half and MY OWN time wasted trying to resolve, I received some of the codes.<br> Currently 1 voucher code for an A3 canvas is still outstanding.<br> <br> Printstagram keeps telling me to contact Groupon and Groupon keep telling me to speak to Printstagram.... this is going nowhere !!!!!! no response to my emails and i cant get through on the phone lines<br> <br> <br> now what??
