I bought a house in 2003 with boi mortgage which was fixed at 2.99% for first 12 months, after which time I received a letter with 7 options including a tracker at 3.3%. If you didn't reply to letter (which i didn't) you were put on a 3.6% variable rate by default. Should the cheaper tracker have been the default setting? Have I any case to fight?
Do you have any reason to doubt that the default option (in the absence of any election on your part) was a standard variable rate as determined by the bank from time to time? If not, what case could you have?
