Disappointed with Discovery Bank

I am a client of Discovery Bank and very happy. My mother then asked me to get a credit card for her because she saw all the benefits I receive. Today she got a call and said her application was declined. They asked about her income and she told them that she gets social security. She doesn't get a proof of that, but it shows in her bank account. She also told them that she gets a pension income from my late father's fund from Eskom. She haven't received that slips yet since his passing. She also gets annuity income from investments from annuities with Discovery. My mother has numerous investments with Discovery of over R1 million.

So I cannot see how you can decline a Gold card application for her. You can clearly see on her bank statements that she get an income. The decline letter didn't even show the reasons for the decline. With service like this make you wonder if it is still worth her while to keep the investments with Discovery.
