Groupon Sa
No promised refund after a month

I bought LED light through Groupon on 1 Nov 2013. I bought 2 sets and paid for two. One with my credit and one from my ABSA account.
Ganeefa Leeman replied and indicated that the items will be send. I received one and I enquired about the other one.
Ganeefa Leeman requested my banking details for the refund as they have made a mistake. I replied immediately with the information, but until today, I have not received the refund. I have send several emails and no response.

The ticket for this is (Ticket #86951)

Do not phone me, please reply via email
