Address “corrected”. What can I do?

My apartment is on the back side of an apartment building so it’s not visible from the street. It’s constantly a struggle to get things delivered by UPS & FedEx (despite the landlord putting up big sign on the front of the building saying “MORE APARTMENTS THIS WAY ➡️” because of this). I have a SmartPost/Ground Economy shipment that has been scheduled for delivery by FedEx, not the post office. The driver decided that my address doesn’t exist and kindly corrected it for me, except that it does exist. I can’t manage the delivery because it is a Ground Economy shipment. I can see when I log into my FedEx profile that the address entered by the merchant is indeed right and didn’t need correction. Is there a way for me to see what the address was corrected to, or some way to intercept it before they deliver it who knows where? Or, will they end up actually giving it to the post office for them to deal with?
