Capitec refusing me a credit card based on my age.

I changed banks and went to Capitec. I was helped by a lady at the Somerset Mall branch.I stated my requirements for banking with Capitec, these were, a investment account (fixed deposit) ,a cheque account, and a savings account ,plus a credit card. After transferring funds from my old bank to Capitec, placing certain funds in different accounts within the system, I then app**** for my Credit card, I supp**** all documentation as required by Capitec. My transferred funds were quite substantial, I was then told by the agent servicing me ,that, due to the fact I was over the age of 65 I did not qualify for a Capitec credit card. I am going to try to resolve this once more ,if I am not successful in that I will be moving on to another bank, I have held a credit card for about 40 years for quite a substantial amount , have a credit rating close to 700 , and I am refused a credit card because of my age, how crazy can you get, I can walk into any other bank in South Africa and qualify for a stand alone credit card and get it, yet my own bank refuses me a credit card based on my age alone. I look forward to hearing from Capitec whose campus is just up the road from me.
