Why no discount for pensioners

My wife and I are clients of capitec for about ten years. We also have savings accounts with Nedbank. Nedbank has a discount structure for clients over 55 years. (We are in our 70s). Nedbank do not charge for payments via EFT but capitec charges two rands each for the etf's. Also, capitec charges three rand for stop orders (used to be R3.50 each). Nedbank do not charge anything. We do regular payments to various charities monthly (about 12 -14 different ones) and it's free from Nedbank but greedy capitec charges. Most banks have a discount for clients over 55-60 years EXCEPT greedy capitec.
