This was carried out in October 13th-20th 2014 then spoke to them several times over October, November and December as was the case with the CSA. Both organisations seem unwilling to take my word for anything.
Yes, I did this over the phone on 2 occasions because that is what CSA advised my to do because they have continued to take maintenance payments off me for over the last three months. The child benefit office will never advise me on what progress has been made because apparently it is none of my business even though I'm being relieved of about £300 per month.
Yes this was carried out in November and again in December 2013 although, am not allowed to be given feedback from Child benefit office for progress.
