I have been sending my daughter to private nursery for the past two years. Have already spent around £42k. I was told today that they have been under charging me and four other full time parents for the past few months (they didn't add a fee increase apparently) and now expect us to pay over £1k back to them. The nursery is a huge chain, and I don't have a spare £1k floating around. The other parents that owe the money are all full time too (so we are the only ones it has an impact on! Has anyone got any advice? For the sake of £4K to a huge chain, I would expect them to just take the hit as it their mistake?
