OK! Had a mum start her boy with me, signed contracts couple of weeks back, no settling in sessions as he was coming straight from previous minder, he came first day today, was sick this morning, sent home as per policy, mum then sends vague text asking about the "cooling off" period. Mine is within first two weeks you can terminate without normal 4 weeks notice. Mum has paid for first week in advance today. She has now texted saying - she's not happy and wants boy to be with family instead, also implying I have lied about him being sick and wants first week fees back. I've replied saying as per terms of contract ( I use MM ones) if you decided to withdraw your child for whatever reason then fees paid still stand. She is being shirty about it now Really don't need it and feel ****** annoyed to be fair as I turned down another woman who wanted the place for her son as she came to me first.

Advice on how to deal with awkward types please?
