And still, the vast majority of posters are coming here to say "poor carers" and barely a one to have any sympathy for OP, who's alone, isolated and not receiving the care she desperately needs.
If she calls the care service, she's not making a personal complsint about the carers. She's complaining to the management of the company providing the care. And she needs to.
Seriously, it's like haven't anyone here can imagine what it's like for OP. Ffs use your imagination, have some empathy, and stop using her thread to tell her (or at least imply) that she's unreasonable to complain that she's been left unfed and untoileted from the night before until after 1pm.
It doesn't matter how bad things are for care agencies, these situations need to be logged for anyone to eventually take any notice.
As had been said by a care manager on this thread, this is a safeguarding issue. No food, no drunk, no toileting, no personal care. Who would accept that for themselves, for their child, or for a loved one?
