Total idiot. Wanted to pay money into my tax free childcare account for the first time. I wrote down the account number, sort code and reference, logged into my bank to do the payment, doubled checked and triple checked the account number and sort code so I didn't muck it up - then totally forgot to add the reference number I'd be given! Now panicking. Will have to phone the Gov helpline tomorrow I guess. Really hoping it'll be simple. Worried I've lost the money! Any reassurance?
