Just a quick update, the person who told MissOops that she had been seriously overpaid is no longer with the department that told her. The person who conducted her first interview to establish her benefits has also moved on.
She has been overpaid on the bedroom allowance for 2 years, the amount of the overpayment is £3k, bad enough but not as bad as we thought.
As she has kept all of the copies of the forms that she filled in 2 years ago, which clearly states the property details she was in at the time, she is going to appeal, just out of principal as she knows that she will have to pay the money back, in fact they will deduct it from her payments.
It could have been worse! Thanks for all the helpful comments. But as a quickie, after an initial interview with the Benefits office, all forms to be filled in and all communications are now online in a ‘Journal’ no telephone calls and definitely no face to face any more, no emails either, all done via the phone/internet. That’s progress for ya!
