No Response when Groupon must refund the customer

On the 21st Dec i ordered 2 Tom Tom tablets, it stated that delivery would take place in 96hrs to Cpt, 2 days later it then showed delivery would only be during the 1st 2 weeks of Jan, i then emailed support to cancel my order, got a reply from Shana stating that she has spoken to courier company and should it come to me i should refuse and then she would ensure i got refunded. Today i called the call centre and waited 25min before my call was answered by Tasneem and she advised me that Shana would email me today regarding my refund as it was being processed. I guess the joke is on me because i received no email from Shana regarding anything. When its comes to paying for your goods then they want their money immediately but when they need to refund, its a mission.
