this is exactly what happened me, got mortgage approval in dec 07 for tracker ecb +.8%, have letters with this in black and white, waited for house to be finished (aug08)to draw it down, in may 08 got a new offer of ecb tracker - what ever ptsb tracker rate was when the 2 year fixed rate ended, i signed up to this unknowing what the tracker rate would be but thought it might be ok, roll on aug 2010 and the letter of offer was ecb +3.25%, i nearly got sick as i missed out on the lower tracker rate by 8 weeks, i put it writing to the bank but they said i signed up to the higher rate, have the complaint gone to the ombudsman, they invited ptsb to discuss it between the 3 of us, ptsb declined, ombudsman are going to investigate it further, havent heard anything in 2 months as there is a waiting list, its similar to op's situation, i thought i wouldnt have much hope but reading here has giving me some hope that it can be recified, ecb +3.25 is ok to have now but when rates rise i will be in trouble so hope the ombudsman can do something
