Day Nurseries Owned by Whanau Day Nurseries in Hertfordshire

We have been incredibly let down by this nursery. My son attended for nearly two and a half years, and my young daughter was due to join him with us having had a space confirmed and our deposit paid. Three months before she was due to start, the nursery informed us that due to an admin error, there was in fact no place available for her with little explanation given.
We have had to deal with a lot of unnecessary stress finding her (and my son) an alternative setting at short notice which resulted in me having to delay going back to work.

In terms of the nursery setting staff turnover seems to be very high, new staff rarely introduce themselves and there were times we were unaware of who my child's key worker was.

Nursery director flatly refused to allow my son to be potty trained as she personally considered it unhygienic and explained that they do not do potty training in the under-2 room. Once my son changed the nursery, the new nursery were happy to support me in this task, so not clear why they could not do it.
The child was often returned dirty, I had to raise this on numerous occasions, but it did not seem to work. Staff wear long fake nails so not clear how they manage to take care of children.
My son’s key worker was changed but we were never introduced until we eventually left the nursery. Names were constantly misspelt in emails, I reported issues in the nursery but they were acted upon only after a month of chasing.
Staff are constantly changing and are inexperienced, the manager changed 3 times in less than a 9 month period.

I was unhappy and filed official complaint, nursery director forgot about it and tried to resolve issues by saying that I better leave the setting.
