Oh Ken...I agree with Martha; you absolutely did the right thing.
Just so sorry for this unexcusable experience for your Betsy...
Keep on 'em...let them know when she isn't being kept clean...I'd be at the administrator's door also. There are laws in place to prevent things like this from happening. I'm so very lucky for the care my Mom gets.......
If you see good changes in Betsy's care, make sure you mention this to them too...it could be they were simply caught in between care...but if this is a common problem...it needs to be addressed.
Vent away....we're here to listen and offer shoulders.......Pam
