DD is 17, in September she started work for a well known clothes shop. She took time off due to MH and they effectively didn't keep her on as she'd only been there a few weeks.
She received her final wage in October which was a normal wage and stated she had sick pay on there.
Fast forward to this weekend they've sent her a letter saying she was paid in error and she owes them £600 which they want back in 2 weeks!
DD is currently waiting for her DBS to come back and awaiting a start date for a new job so has absolutely no means of paying it, neither do I.
OH says to ignore it, it's their mistake and it's been months but I don't want them to take her to court.
Does she have to pay it?
