I have £1200 childcare vouchers that I will not use. DCs are 11,11 and 13 and no longer need after-school care. DP has gone from working away from home for extended periods to working from home. I'm a teacher so we don't need holiday clubs either. I've claimed the maximum £243 for 13 years and it just didn't occur to me to cancel 
My employer contacted the voucher provider (Fair Care) today on my behalf but they have refused a refund because there are not 'exceptional circumstances'.
I know it was an oversight on my part but at the end of the day it's my hard-earned salary sitting in an account somewhere and I would like it, or part of it even, back!
Has anyone experience of this? Or any advice?
