I gave one month's notice to my child's nursery on 11 August and asked that the last date she attends nursery would be 12 September. The contract states that I need to give one full calendar month's notice. The nursery is now stating that I need to pay till 30 September and not till 12 September. We basically disagree on the definition of 'full calendar month notice'. My interpretation is 30 days while the nursery interprets it as the end of next month (unless you give notice on the 1st of the month). My argument with them is that the term 'full calendar month' is ambiguous as it can mean both things and had we known it meant this we would have given notice on the 1 August.
Can anyone advise?
