We are fixed with St George, it unfixes next year. It has worked out perfectly, as we missed all the rate rises, and it evened out, which has been great while I have been building up a business and having bub number 2 . At the time it actually saved us $50 a week, but once the rates went up it saved us so, so much more.
I have found St George awesome to deal with all along, their service is excellent, I couldn't recommend them enough!! Because we have a home loan with them, we get Gold service, so I have a different number to ring which mean I always get an operator straight away. The one time I did have a complaint regarding fee's on our saving acc, (the manager I spoke to would not help), I actually emailed their complaints department, and within 2 hours I had a call back, and all fee's credited back in my account (it was over $100 worth).
