Hi Ferrety, it is likely that the mortgage you saw in the paper relates to new mortgages, what you had to pay would have to be set out in the terms and conditions in your mortgage at the time you took it out.
There is probably not alot you can do in relation to the arrangement fee or the Early Repayment charge but do check your mortgage agreement to make sure that the sums are correct.
The Final redemption Charge sounds like the mortgage exit admin fee which were reviewed by the FSA last year. Many of these were found to be above that stated in the original contract agreement and companies had to provide a refund of the difference where customers complained.
Take a look through the mortgage forum here:

and specificaly to the exit admin fee see here:

All the best
