Standard bank

I have paid up my credit card in full and I had to call standard bank card division to close the account and email me a settlement letter. I am so disappointed and disgraced on their services. I was transferred to 3 consultant and I was on the phone for over 30min just to get a settlement letter and to close the account. All three consultants had to ask me security question and I eventually ran out of air time. Standard bank card division their services are very bad
