i took out an offset mortgage with Inteligence Finance about 5 years ago, after looking at there advertising demo showing how offsetting can help finish the mortgage early it seemed exactly what i wanted .
Having made extra mortgage payments & have a savings account with £10,000 & a current account with approx £1,200 a month going through it .This i thought would of made a fair impact on the capital outstanding and term reduction. I have contacted IF on numerous occassions curious as to how much difference this offsetting has made to my mortgage so far , as yet they seem unable to give me any idea ! they say it is due to the complex calculations involved .Is it me being thick

or is this usual ?..I have spoken to Nat West who market a similiar product and they assure me they give monthly figures regarding the offsetting and the current position. I am tempted to change lenders but i need to justify the costs and hassle involved..Any comments/help would be greatly appreciated ...
