Terrible Service, Zero Communication, Unknown and Unnecessary Delays

I have been waiting for a parcel delivery for the last 2 days, sitting patiently at home. The parcel was initially scheduled for delivery on 11 April 2022. By 5pm it had not arrived and the tracking status read "Customer not available or business closed", so I called customer service. I told them that I was at home waiting for the parcel all day, so I was 100% available. The lady on the phone asked to confirm my address, and it turned out that they did not have the unit number in my complex (though I am peeved that the driver didn't call me on my cell phone when they arrived and realised they didn't have the unit number). I am not sure how this error occurred, but we corrected the address over the phone and the driver was told to call me if there was any difficulty or if they needed directions. The delivery was rescheduled for 12 April 2022.

Today, 12 April 2022, I sit at home again awaiting the delivery. At 2pm, I checked the tracking. Once more, the status read "Customer not available or business closed". I called customer service again to enquire and express my frustration. The woman on the phone again checked my address, which was still not correct. We confirmed my address on the phone and she asked me to hold while she called the driver to see if he was in the area and could deliver my parcel. When she got back to me, she confirmed that the driver actually had the correct address (who knows how, considering it was incorrect on the system), but that operations had called him and told him not to deliver my parcel.

Firstly, I am flabbergasted that the driver did not call me when he realised he didn't have the unit number - it would have been a quick fix. Secondly, I am outraged at whoever from operations told the driver not do deliver my parcel. Why on earth would they do that, when it had already been on board the vehicle twice? What authority do they have to decide that it should not be delivered? Why have I not been contacted/informed about the delay? And what exactly is the delay? The lovely woman on the phone did not know the reason. This courier service is shockingly bad and the communication is non-existent. I will never recommend or use FedEx in the future. It will be a miracle if I ever receive this parcel.
