Mango support for voyager miles not working

<p>Mango, has now said they support payment using SAA voyager miles. However attempting to use voyager miles to pay results in a pop up saying "insufficient mile. must have more than 5000 miles". I have logged into voyager account multiple times and verified that not only do I have way more than the "5000" miles available I have way more that what is required for the flight. When I called Mango to query this the agent just told me there is a problem and I must use another payment option. Not sure how this helpful as I want to use the miles I have to book the flight.</p>
