REFUND NOT PAID BACK TO CLIENT

I purchased a Groupon voucher on the 27/10/15 *** for an amount of R796.00. In error Absa Bank deposited R800 to Groupon.<br> On contacting Groupon on the 28/10/2015 I was advised that I have to repurchase the voucher as the amount was incorrect and the R800 would be reimbursed to me.<br> I sent my banking details to Groupon on the 28/10/15 to Faadil and received a mail from him the same day that the refund would take 5-7 working days.<br> You sent me an email on the 30/10/15 advising that the money should be in my account within 1-3 working days via Worldpay AP Payment System.<br> I called on the 4/11/15 regarding the refund and was advised that the money has been processed and should reflect by Friday 06/11/15.<br> <br> It is now 9 working days later and the money is still not in my account. On calling your offices today Faadil says I must wait until Wednesday 11/11/15,well I'm tired of waiting for my money.<br> Every time I contact you the day of refund changes
