Discovery Makro voucher debacle (still waiting after a month)

Discovery's active rewards system is a complete shambles!

I cashed in some Active Rewards coins at the end of last year to get R500 worth of Makro vouchers (2 of them). Tried using them early December and they didn't work so I was sent new ones. Then I was told those wouldn't work and I would be sent replacements but I only received 1. I have been trying for over a month to get this resolved with no joy. The last response I had on this was on the 17th of January almost 2 weeks ago - they don't respond to e-mails any more. In addition they have messed up some coffee vouchers - still no joy 2 weeks later.

Discovery is becoming a complete joke - I am spending more of my time chasing them up than the value I get from the rewards. What is happening over there?

And I am not the only one - I have friends who have had similar experiences.
