They owe me R2200 and are ignoring my emails.

On the 3rd of December 2014 I ordered two sun Lounger chairs. They each cost R1099. First they delivered the one after three weeks. I waited for the other one until January 20 when I got a response stating that they are out of stock. I then told them to fetch the one I have and give a full refund as I didn't only want one. When they fetched it, the other one arrived. I was, yet again, stuck with one. Contacted them and organised that it be fetched and they said they would get back to me within a week, after an inspection. This was end January. It is currently the 10th of may. No product, no refund, no response. They owe me R2200. They are even ignoring all my emails and don't get back to me when I call. So many times I have told myself that I won't ever use them again because they are ************* and unreliable. This was the last. Groupon is not the kind of place one wants to buy things! Don't make that mistake.
