No help for mum

Last month, mother in laws doctor sent a referal to Social services for them to call and see her and carry out an assessment in order to help us put a package in place to meet her care needs. As a family who have never had any dealing with social services before, we had no clue how to get the ball rolling. She has Dementia and the memory clinic assigned me a support worker as they were concerned I have taken on too much with her care. However.....there is nobody else local to help us in anyway....so....what can we do?
At present, hubs and i visit her daily. In two weeks, hubs goes into hospital for an op and can not drive for 2 weeks after and i dont drive. Also, i will be back to work when school starts up. We were informed we could probably get crisis care for those 2 weeks. But....yesterday, i got a call from the social worker who visted Mum and she told me in her opinion, mum doesnt need any support so they are not going to provide us with any help or support to come up with a care package. She said mum clearly manages to meet all her own care needs and her house is spotless. Of course it is...coz we go there everyday and clean the kitchen, get rid of her rubbish etc.
So ..... dunno what will happen to her that week we cant get there....
