Poor service = lost of revenue

I opened an account with Discovery Bank. From the onset I had issues with them. Thank God I didn't close my Nedbank account. I have also app**** for a credit card to benefit from being a Vitality member but was declined. Funny thing is that Nedbank approved me within 24 hours with a ridiculously high limit. I'm puzzled as to what criteria Discovery uses. All that I can say is that I am slowly moving away from their products
