Before we moved mum in with us, she lived alone and had 4 x carers visits daily. She too wouldn't let them do a thing but it was for our peace of mind, as you say, if she fell etc. Mums first call was not meant to be before 10.30am due to mum being awake a lot at night but I caught them red handed on many occasions, one in particular I went over on a Saturday morning early as mum had hair appointment. I arrived at 8.30am and noticed the carers had been in and written in the book that mum was ok, and nothing required. They wrote down the times as 9-9.30am!!!! I was furious and phoned the agency immediately to complain. There was a sink full of washing up they could've done but didn't, the bin needed emptying but that was left. The least they can do even if mum refuses their help is to sit and chat with her over a cup of tea. If they have half an hour, an hour or 3, they should be there for that time. This was one of many things we complained about. We too had the 18 years old strolling all dolled up like they were going clubbing, no conversation, mum getting all agitated because of the way they approached her, was a nightmare. I complained to the CQC and then got mum swapped to another agency who were better, and supplied older lady carers who had more life skills and at least could have a conversation with mum!! Don't put up with it, its an appalling state of affairs when this happens and I always think if we don't complain about it, it will happen to those who have no one to stand up for them.
