Hi bad manners and welcome to the forum
I hope that this has not actually happened to you, but if so talk to your IP as soon as possible to alert them to the problems you are experiencing.
When you say the payments were set too high - was this based upon information you provided to the IP, or was the IP telling you what you could and could not spend? And are you saying that you made amendments to your IVA proposal which were not considered by the IP?
