No spending the Discovery Miles you've earned!

I have been trying since the 12th June to use my Disocvery miles to make a purchase. I have been completely unsuccessful and keep getting told by your call centre that there is no turnaround date, does this mean I will never be able to spend these miles, I earned, in a way I want to? From the 12th-16th June I was using Cape Union Mart's website and from the 23rd June until today I have been attempting to buy products off Takealot's website with no success. I expected better from a company I greatly admire!<br> <br> When I select pay with Discovery miles, the slogan comes up: \You've earned your Discovery Miles
