Fed-Ex is in the scope of things, one of the least you would expect this type of problem with. The USPS......yah, To many are low motivated, and follow the creed of 'It will get there, when it gets there'. For the Fed-EX shipment, you should be able to track your delivery, on your own, and if in your area, at which substation it is at. If the delay is in system,......aka.....in transit to your city, could it be weather?, a accident (ground-truck?). Station managers will/should be monitoring delayed shipments. Calling the domestic help line (airbill/pkg tracking number) will help get the ball rolling from their side also. Of course, calling your medical supply company will put further pressure on the delivery service to remedy the problem.Maybe more Covid related but diabetics would appreciate the struggle. Fedex has had my insulin now for 3 days and delivery says pending. Impossible to get anyone on the phone. For obvious reasons, I need it now. This covid issue is messing with more people than anything could think of. Even if you don't get the virus.
I worked for a competitive overnight service company for over 35 years, and formal complaints are something Head quarters does look to see resolved. And if it is a driver induced local problem, the station manger should be fixing the problem. Sometimes mistakes can happen, it is the same mistake happening repeatedly, that is a valid concern. Belonging to a local neighborhood chat forum, we had this same problem with a Fed-Ex driver, first mis-delivering to the wrong house, and then,.....DELIVERING THE WHOLE STREETS SHIPMENTS TO JUST ONE HOUSE ON THE BLOCK, like Santa's bag being lost. Obviously this was abnormal, and individually a driver induced problem (personal issues) who is now gone we believe, as the problem went away.
I'm glad this OP was made, and too those who have responded, as it puts out in the open, the challenges we face for being able to get out and travel, enjoying that which limited our ability in the past. Not all of us can afford an electric fridge, and regulating, your drugs, a challenge in a ice cooler, can be difficult. It is good to see how OB members rise to the challenge.
