How to navigate aged care packages

We had a bad experience.
I have received an assessment.
All I need is someone to mow the lawn.
One provider wanted 26% of the assessment.
I asked whether I could buy an oxygen concentrator out of the money. I was told yes.
The machine costs $5,000. I was told to get all the details and give it to them. They would then add 26% to the cost of the machine and then order it, When they receive it they would then add a further 26% to it and then deliver it to me. This machine would then cost $7,938.
What a racket.
In addition to this, if a did sign up I would lose my pension.
This is a racket.
Another Incident.
I am 78 years old and have a chronic condition.
Age Care came out and advised me I need to change my bathroom to suite my condition.
Age Care would put $10,000 towards it, but I need to use Vision Australia.
I received a quote from them for $38,000 less $10,000= $28,000.
I received a quote from another party for $27,000 which included a toilet. I asked whether I can still get the $10,000 to help and got told NO.
I consider both need to be reviewed. As a suggestion is maybe Age Care obtain three quotes and let the patient choose who they want.

Very disappointed with how Age Care operate.
