Do you have the Tracking Number for the original?
What is the exact wording it gives?
Royal Mail did this to me just before Christmas - again with a BT hub. Hammer Royal Mail about it as they seem to treat BT deliveries badly - my Wednesday despatch should have been here on Thursday, but the RM site moved it to Friday and it was out for delivery all day but did not arrive. Then, it was "delivered" at 08:00 exactly on Saturday - but he finally appeared with it at 11:10 and denied doing a delivery scan at 08:00.
Tell RM you want answers and you want them by 14:00 today - you are not prepared to wait longer. Indicate that their claim to have delivered is a lie and potentially fraud. Insist that the next delivery will be expedited and delivered before 09:00 tomorrow - they will say no, but it can be done with the depot manager's intervention.
To get over the problem, you might be able to use your existing hub - what is it? Someone should be able to advise.
