The Tynwald Commissioner for Administration says there are markers of maladministration by the Post Office in a complaint over a £1.90 parcel.
The commissioner was contacted after the Post Office mistakenly sent the recorded item containing legal documents to the UK.
The person who sent the package complained after it took two months to get a refund - the commissioner said they'd found markers of maladministration in the way the matter was handled.
But the report on the incident, which will be laid before Tynwald in July, found the delays in refunding the postage costs didn't involve any wrongdoing by the Post Office.
