FNB credit card department pathetic

I have a credit card with FNB over 20 years. I go to the branch in Bedfordview 17 June to increase the facility limit on the card only to be told that there is bureau block on my account. The consultant cannot assist with this query. I must call TransUnion and check what's the block. I called TransUnion and they confirmed all my accounts are in order. I go back to the bank only to be told I must call the credit card department for FNB and send them a report on my credit record. It's getting more frustrating to have a bank account in SA, you have to do the admin yourself. Why on earth do we pay banking fees, get charged with admin fees. What assistance is the client getting. Will it get any better in this country. Is there a better credit card department in the banking sector instead of FNB.
