No refund yet / Bad call centre

I purchased a Groupon voucher for the Love to Bake cake deal in Pretoria. The supplier of the cake made a mess of my order and we agreed that she will refund me. <br> <br> 14/11/2015 - The supply sent me an email confirming that she had requested Groupon to refund me. <br> <br> I waited two weeks and there was no feedback from the supplier or Groupon.<br> <br> 30/11/2015 - I forwarded the suppliers email and voucher to [URL Removed] and received an automatic response that refunds are usually processed within 3 to 5 days. <br> <br> 04/12/2015 - I received an email from Groupon stating that they were dealing with \unusually high volumes of emails"and I should phone their call centre for urgent assistance. <br> <br> I've been phoning the call centre since 14/12/2015 and they are constantly dealing with high call volumes and my calls get disconnected immediately after listening to the recorded voice. I don't believe that processing a refund when the supplier has confirmed it should be this difficult. This could possibly be the last time I ever deal with Groupon as their customer service is below standard!<br> """
