Refund owing for 2 weeks

On 22nd December I placed an order for flowers, using a R200 gift voucher and paying the balance with Discovery Miles. I then cancelled the order within a few minutes. It is now the 18th January and I am still waiting for my refund. I have called numerous times, and I always get the same inane answer, your refund has been approved and will be in your account in the next 3 days. WHY keep lying to me. There is no refund. This was the latest message on the 4th January Hi, We’ve received your request for a refund. Your order has been referred to our accounts department, who will be processing your refund. Please note, the refund should reflect in your account within 72 working hours. Should you review your bank statements, the refund will appear at the date of the original payment.
