Caring carers

Hi, Does anyone have experience of using carers in Paris? My disabled friend with MS is unable to find carers who actually care: she has tried many different agencies, always with the same poor results, meaning that she is now receiving shockingly poor care, tantamount to neglect. She needs people who just do their jobs properly and with a modicum of care, but this seems to be impossible. If anyone can recommend someone they've used, or even if you know whether there's a watchdog organisation for care providers, I'd be really interested. Thank you!
