We're aware there are delays with some customer orders not yet showing on our returns portal. The error may look similar to this:
If your order was shipped in the last few days and you’re seeing this error – we would recommend you check back in a couple of days and try again. Your order will appear, it’s just taking a few days longer than normal.
Our Customer Service teams are also impacted by the same delay so are also unable to schedule a return which is experiencing this problem.
Please be assured our technical teams are working on fixing this issue. Sorry for any inconvenience.
