Absolutely! Without fail. Contact CQC immediately! They WILL protect your anonymity and you'll feel better for having done this. We fail our elderly and vulnerable on an appalling level. These homes should be prosecuted for this.
I, for one, would not contact the owners direct; you'd most likely be seen as a trouble maker and forced out.
Please, please contact CQC, (be sure to get the name of the person you speak with!), make your concerns known to them and they will respond immediately. If you fail to see action within one business week, then call back, ask for a 'lead' or 'manager,' share what has happened and inform them that as there has been no action on CQC's part, you're contacting Dispatches at Channel 4.
I assure you, they'll move faster than snot on a doorknob!
Well done you for being concerned. There should be more like you!
