Hi bazc and welcome to the forum
Your IP company should have advised you whether it would be worth offering a variation to the terms of your arrangement in order to accomodate your recent changes in circumstances.
I can understand the car issue - obviously this occured as a result of unplanned circumstances outside of your control, but clearly your wife giving up work was planned and could possibly have been avoided. Is she in an IVA as well?
If you feel that you have been badly treated by your IP company, and if they have ignored correspondence you have sent to them to explain your circumstances, you should firstly enquire as to their internal complaints procedure and identify the name of the person who deals with such matters. Then write a letter explaining your concerns, asking him/her to investigate the matter on your behalf.
Matters like this usually result from communication difficulties, and are generally resolved with little fuss.
