:mad::mad: hello I got a mortgage in Dec 2006 this was on a fixed rate for 5 years it then went on to the svr after this.

I got a letter this morning and it gave a leaflet saying what mortgage conditions I should look at for December 2006.
I looked at the book I still had and it says that

if the increase applies to whole of the capital you will be entitled to repay all the money you owe us within three months from the date on which the increase takes effect, without paying any early repayment charge that would otherwise apply.

if the increase applies only to part of the capita (the affected part) you will be entitled to repay the money you owe us or (the affected part) within 3 months from the date on which the increase takes affect without paying any early repayment charge that would otherwise apply to the affected part.

I spoke to a mn this morning before I looked for this booklet and he said it didn't affect me and that was it.
I found the booklet and went through it and this is what it says above.

so again I rang them this time I spoke to a lady she again said it didn't affect me.
I told her I got the mortgage in December 2006 and that it was fixed for 5 years and I also read the statement above and said that this did in fact affect me.
her attitude changed and she was off hand and than she asked me would I have changed anything about my mortgage back then and I said yes I would of looked elsewhere for a better deal
she said I would have to fill in a questionnaire and would take 15 min over the phone

I then asked for it to be sent to me as I would like to go over the questions they want.
I am so mad that they were trying to fob me off yes I may not get anything but this is not the point both of them said no when I asked if it affected me but I read them what it said in my mortgage conditions booklet of 2006
