Discovery Card has dropped their cashback benefits without adequately informing clients

Discovery Card dropped a whole lot of their benefits without properly informing their clients. No longer cashback at so many retailers. Example, I was still using my Discovery Card to purchase at Nandos, thinking I was getting cashback, but was not. Discovery Card had almost quietly dropped all of these cashback benefits. They switched to “miles” which you can use on SAA ( I DONOT fly SAA). What makes matters worse is that they are CHARGING me an annual fee of R435,79 for this “miles” benefit. This charge, together with their monthly “Credit Facility Service Fee” of R16,14 AND their monthly “Credit Card Account Fee” of R43,38 gives them a total annual fee of R1150. This is a huge amount when compared to credit cards from other banks. I only took out this card with Discovery because of their cashbacks that they boasted about and promoted. Now that they have slyly removed these benefits, they are not worth it. Only when I enquired about the R435,79 charge, was I informed and what benefit it was to me, was I informed that this was to replace the previous cashback benefits. I told the agent that I would be complaining to the Consumer Commission, Banking Ombud and Financial Services Board. This resulted in an offer to reverse their R435,79 charge. I will still be complaining to the relevant bodies, because this is unfair to other clients who are not aware that the benefits have been reduced.
