I have an IVA in place jointly with my wife, we have not recently paid the monthly payment as we were advised that this was the right thing to do, the company which advised us of this has since vanished and we cant get hold of them, should I re instate my payment.
It looks like you have fallen victim to a scam from a 'bankruptcy assist' company. Your IP will have come across this before and can help so hopefully they have not failed it yet.
