A have a parent who pays by direct debit each week but the hours have reduced recently and so should the weekly amount she should pay me. I gave her 4 weeks notice to change her direct debit but 8 weeks on from that she is still overpaying me each week. I am scrabbling about for change each week to refund the difference.

She is driving me mad now, she says she has been to the bank, rang them up to change it and all sorts, but now I am starting to think she is on the fiddle with her tax credits.

How do I account for this? Do I enter the overpaid direct debit as income and then put the refund/change as an expense?
