LTL shipping


Hi it the first time i am using amazon partner carriers to ship LTL
i choose it on the shipment page and approved the prices. scheduled a pickup date to 26.5.2020
no contact person details or phone number was asked nor given and i see now it is scheduled to 26.5.2020 3 am UTC which is 23:00 pm
i don’t think the warehouse where the goods are is open at those hours
does anyone has experience with this?
