I made a purchase for £176, however the retailer made debit card withdrawal of £676.
I recorded the £676 debit as payment against the £176 purchase, leaving £500 of the debit payment as unallocated. I then received a £500 credit from the retailer.
Any advice on how I can resolve the unallocated amount and credit would be much appreciated.
Go to the part-unallocated payment (purchases -> all payments -> advanced search -> type “unallocated” is probably the quickest way there) and at the top there’s a “refund balance” button. This will create a new pre-tagged bank transaction, so if you already have an untagged £500 transaction you’ll need to delete that, leaving just the tagged one.
