QUESTIONABLE INTERNET BANKING PRACTICES

I bank with Absa and have a Standard bank credit card. I recently got a new Standard bank credit card.I have previously had Standard bank credit cards listed as beneficiaries on my Absa accounts. Today I tried listing my new Standard bank credit card as a beneficiary on my Absa account . There was no way of listing the new credit card as a beneficiary.Is Absa trying to stop their clients from using another banks credit cards ,or is it just a poorly constructed internet banking site.Please let me urgently know.Maybe this is a case for the competition commission to look at .
