Disgusting service and trweatment of clients

The worst service I have every received. My credit card indicates large double charges. After 6 phone attempts and being transferred from pillar to post with the call always dropping during a transfer, I finally get through to a gentleman who asks me all the security questions on the credit card account which are answered correctly. He then asks a question on my personal account that is not linked to the credit card account and says that I answered the question incorrectly, I challenged this but was told that I must phone back after 24 hours. Personally, I think he just didn't feel like assisting me as it was the afternoon before a long weekend. As soon as possible, I will be closing all my Standard Bank accounts which I have had for more than 30 years.
