If there has been no change in your financial circumstances, then I cannon see who this firm can have increased your disposable income so much - but you also share the responsibility for not checking the figures properly at the time. Where did you feel that the additional income was going to come from?
If you feel that you have been badly advised, you ought to firstly take this up with the IP concerned and ask them for an explanation. If you get no joy with this then you could refer the matter to the Financial Ombudsman or their regulatory body, but I rather feel that the matter will be referred back to yourselves for agreeing such a high repayment in the first place.
Have you considered whether bankruptcy proceedings would now be a better option, and do you have any assets which would be at risk under such proceedings?
