Thanks for the support, its much appreciated.
I found Disability adovates on Facebook. This is what their page states
We are a passionate community dedicated to championing the rights, inclusion, and voices of disabled people across the UK.
Our mission is to raise awareness, challenge inequality, and provide support, guidance, and advocacy.
I also contacted them and asked who they are.
They replied with:
We are an advocacy service. 2 of the team worked for local authorities in their welfare rights service and we have a barrister who works pro bono with us. We have offered our services for 3 years total now.
