I am currently repaying a pretty large debt through step change. I have gone online to renew plan and kept most of the figures the same. The big change that I have put in is no longer receiving child benefit. However I have included child pocket money as I do contribute a little towards Dd at uni and couldn't find place for that. Admittedly some of other expenses a guesstimate. It won't accept plan and have been told to call.
Anyway anyone had experience of this?
