I placed a reservation on a publication and received an email notification regarding its availability for pickup. I received a further email confirming the item had been checked out. I do not have the item in my possession. What steps should I take?

To secure your reservation, the procedure for sending the item(s) to the library designated as the pickup location involves us pre-checking out the item(s) in your name for a period of 2 business days, starting from the availability date.
The item(s) is/are forwarded to the selected pickup library immediately after this checkout.
