In the comments box on your future PV orders, you can specify you want them to use UPS instead of Fedex. That's what I do after having a similar series of issues with Fedex myself. Works great!
While on the topic of lazy, lying drivers . . . the only ones I've found worse than Fedex are the drivers from the new "Uber-like" services that are being used by (eg) Amazon (AMZL US). Especially around Christmas
