Nedbank Greenbacks Website a Joke

On 23 April I went onto the Greenbacks website and opted to pay my monthly credit card installment using some of my Greenbacks points - this is an option on the website. However, my payment never reflected and since then it has been the biggest hassle to try and sort this out.

It has been a continuous back and forth between the complaints, greenbacks and credit card divisions. No one seems to know what's going on. The credit card division didn't even know that this was an option! Pathetic. How do you have people working at service level who don't even know the products.

It is now the 16th of May, nothing is sorted and everyone who promises to get back to me, don't. The payment doesn't reflect on my internet banking, but all the surcharges and processing fees surrounding this transaction sure went through without any failure. How is this possible?

Can someone competent please sort this out for me? What is the point of the Greenbacks rewards program and website if it in fact doesn't even work.
