How do they happen when you've told the tax credits office about all changes as soon as they happen? I've had a letter saying I owe them £1248.20 in overpayments and to pay it in 30 days. I am barely making ends meet as it is. I can't afford to pay them back. I've told them everything as soon as I it happened. Surely it is their responsibility to make the changes to the amounts not mine?
What do I do?
