fed ex is the worst delivery service. using the tracking number on a package does not help much. i had a scheduled delivery due november 30 2021. it was 'updated" by fed ex to november 26 2021. no package arrived. i was advised late november 26 2021 that it would arrive november 27 2021. then the tracking informed me no such tracking number existed. then i was informed it was scheduled to be delivered november 28 2021. november 28th arrives and lo and behold its now scheduled for november 29th 2021. and the real kicker is its been sitting in a fed ex facility less than an hour from my home! for 3 days now. and each update says 'on fed ex vehicle out for delivery! they are worse than the usps.
