Locker unavailable

I bought an item on Vinted. The seller left it in the locker on the 6th of this month. The package is still shown as shipped, but the delivery person has not yet picked it up because the website indicates that the locker is out of service from April 9th to the 19th. Will the delivery person come to pick it up and put it in transit after this date, or should I consider the package lost? Has this happened to you before?
