I was over paid by nearly £8000 a few years back.I presumed it was money we were owed and spent it as they never gave us much and then this amount appeared.It was only when after the annual July rewnual camt hey had got the wrong national insurance number and just take so much back a month which makes things really tight for us.I undertsand that we should pay smoen of it back but dont thinks it fair to pay all of it .They have never owned up to the mistake can we get it reduced somehow as it was their error not ours.
