The retention team at ANZ just got back to me and gave me 6.8% variable, which means 1% off the standard variable for the life of the loans.
They offered me 6.44% fixed for 2-3 years which I don't think I will take.
Just spoke with the retention team at ANZ, they will get back to me on Monday but I think they will reduce my rate down. I have a feeling he knew I was bluffing.
