To be fair, I have had issues w/ all of them:I almost never have a package delivered on time when its routed through Savannah FedEx. I willingly pay whatever difference there is when getting stuff shipped if not using fedex is an option. 75% of the time my packages get put on the truck for delivery and the have an "unsuspected exception" followed by "delivery not attempted". As of right now I have a chewy package that has been sitting in their distribution center for 10 days with a "unknown delivery delay". If its powder or primers from Midsouth, I just have to go up there to get it. They wont even put it on a truck. They have actually left a package sitting next to my mailbox before, all smashed up and on a day where it was raining. Two years at my current house and its been like this the whole time.
UPS: Will not come down my driveway and will not walk across my front yard w/ anything heavy, so I get messages about truck issues. Packages delivered to carport---I don't have a carport (misdelivered).
USPS: Where do I even begin? Misdelivered mail NUMEROUS times. One of which the girlfriend (who works for local USPS) notified them w/in 5 minutes it was misdelivered and they refused to go back and get. 100s of showing as being delivered and it has been handed to her at work or show up days later.
AMAZON: No telling where they will throw it. I have found packages in the ditch up at the road. Behind my truck. On my tailgate.
