I don't think there is anything ambiguous or unclear in this regard in the contract wording.
The FSO
stated in writing to me in its final ruling letter that the Bank (UB) had confirmed in a letter to the FSO that the letter I signed with the para containing prevailing tracker was
not enough to amend the interest rate of the Complainant's loan. This is fact, I have it in writing from the FSO in their findings. If the wording is clear to you fair enough, the Bank have stated in writing to the FSO the above which hardly suggests a clear letter/para?
The Bank/UB took another letter I signed a month beforehand, sought to join the two letters together and argued on the basis of both that I was not entitled to a tracker. Unbelievably the FSO accepted this stating that while both documents were signed on different dates the FSO was satisfied that the two documents formed the basis of the fixed rate agreement between the parties.
The two letters had entirely different paragraphs and wording regarding what would happen after the end of a fixed rate period. The first letter did not state that at the end of a fixed rate period that the standard variable rate applied. However in their communication with the FSO UB misquoted the relevant para from the first letter. Critically when UB set out the para to the FSO it inserted the critical word 'standard' into the para implying that the para said that the svr applied at the end of the fixed term. If did not state this, it said variable rate, of which a tracker is a variable rate. This misrepresentation of key phraseology was repeated twice by the Bank in communications to the FSO. Was this deliberate or an error - one can decide, twice??
Unbelievably, the FSO seems to have completely ignored this misrepresentation, error (whatever label is appropriate) twice by the Bank to it. I do not know if the FSO saw this as important, however it must have, as in its ruling it said that the documents were clear that the svr would apply at the end of the fixed term. The documents did not state that, they actually contradicted each other with two different paragraphs. I was given no opportunity to counteract this as the FSO decision was made and final ruling given to me. My only option would have been the High Court.
Alongside these written communications would have been verbal conversations with Bank personnel who gave assurances re the tracker, etc. Sorry I didn't record them, then again who did?
I am just highlighting that frequently things are not as clear as they might seem with the benefit of hindsight and 10 years of discussion on trackers. As far as I can see one of the central issues is how UB took the FA documentation and used it inappropriately. UB did accept in its written submission to the FSO in my case that the para/letter containing the phrase prevailing tracker was insufficient and inadequate at best.
I have shared information and documentation with the Central Bank last year.
