A mum of two says she has still not been reimbursed after spending £4,000 on a nursery place for her son that should have been free.
Helen, from Nottinghamshire, was entitled to 30 hours of free childcare a week but was charged by the nursery.
The ombudsman said the county council was at fault as it had failed to oversee the nursery's charging policy and ordered it to pay compensation.
The council said it had accepted the ombudsman's recommendations.
However, despite being ordered to repay Helen half of the additional charges, she said she had still not received the money.
