Family member just reached retirement. Recently received a letter stating overpayment, over £400 built up over more than four years at around £2 a week. As far as I'm aware any changes in income, carers allowance or PIP etc have been notified to the council as soon as they happened. I have helped to write an email today stating the overpayment was not the fault of my family member and they always gave the most up to date information on income as soon as possible. I believe another family member has been in contact with Citizens Advice. I feel it's extremely unfair this type of thing happens due to errors on the part of the benefits team. Is there anything else that I can do to help?
