I dithered for ages over which bank to choose and as a result, left it horribly late!! I only faxed off my application to Westpac about five days before we were due to leave, but even so, they responded within 24 hours, sent me banking details within three days and I was able to transfer money over before we left - whew! In the email, they included a 'Why did you choose us?' section and my rather embarrassing answer was 1. because you have a lot of ATMs all over the place! and 2. I liked the sound of the name 'Westpac' - sounds like it means Western Pacific, which is a lot more exotic than the very dreary Standard Bank I have used for the last twenty odd years!
However, so far I am really, really happy with the service which, as Bod Bean said, vastly exceeds anything I have experienced in South Africa. There seemed to be excellent communication between branches, we were expected, we were promptly and efficiently processed with great friendliness, and I now have a savings account and a current account with NO fees at all attached to it at all (unless I get a transaction done in a branch). Plus! my daughter of 17 has her own account which she can transact on just as I do on mine and she can access it online for free - none of this was available to her in SA. So WESTPAC gets a big thumbs up from us so far!!
