I raised a request to return 2 items. When I checked the status the RMA had been re-opened and it mentioned something about removing an item before the request could be accepted. What does this mean?

Depending on circumstances it will not always be possible for us to accept your returns request. If this happens then detailed notes will inform you of the reason and what you should do. Generally you will have to remove that item from your request and resubmit as it is not possible for us to accept part of your request.
