There are tracking numbers CSRs don't like to research them, UPS Ground is used second, UPS 2nd Day is used first, and the delay has nothing to do with discussion between CSR and warehouse. There's a delay in adding shipping information for some customers that haven't previously had shipments sent to them (since 2000.)
Odds are you fall in that last sentence. It should be resolved within two to three days and then there's the standard 72 hours for UPS to do its thing. CSRs really shouldn't be permitted to talk about things they aren't informed of.
Anything else?
