Hello and thanks folks. Spoke to the outreach team, and was introduced to my brother's new care co-ordinator.
I explained the situation, and she said that yes there does appear to have been a problem with my brother's payments. Possibly someone had told them my brother had been sectioned again, when he hadn't!?! See I knew that it wasn't all in his head
Anyways the good news is that the care co-ordinator has been to see him today, and his benefits have now gone in and he is fine.
This is a huge relief for me, especially as no-one was due to go see him tomorrow.
I explained to the care co-ordinator that although these things happen, it had caused me some problems.
I have been promised that they will look into it, and try and get it sorted.
