"Social care experience"

My brother is in his 50s, he has Down's Syndrome and early stage dementia. The social care he is receiving is quite frankly unacceptable. 

At present he has 3 morning visits per week from a care agency. The carers on each occasion  are in the house an average of 5 minutes. Their portal always says he is fine on leaving, whether this is the case or not. Social services now say they have to install tech devices in place of care. 

I find this unacceptable and both my brother and myself are struggling with this situation. 

He has been diagnosed by a physiatrist for mental health for learning difficulties who recommends more care is put in place .

The Speech and language therapist has also advised a carer should be with him at meal times as there is a choking risk. As sister and unpaid carer I am not equipped to care for someone with special complex needs. 

I look forward to a response.  

Thank you
