I received a card to say I missed a delivery with no indication of who it was. I rearranged redelivery. They sent me two emails to say I had requested redelivery but not a single email to say when the redelivery would be. I missed the second redelivery because I didn't know what time or what day it would be on. This card doesn't even say where or when I'm supposed to pick it up.
Short answer is, it's not worth it
