Those boxes look pitiful. If someone delivered anything that looked like that at one of my sites the whole order would be returned immediately. If they came with the finger pointing and the 'no returns' policy you describe they'd be dealing directly with our lawyers long before the stage you're at.

Did you buy directly from Spazio? Did Spazio deliver or was it your courier?

Spazio used to be one step up from the bargain basement lighting such as Radiant, Eurolux, Brightstar etc. I've used their products on several occasions and was never a big fan. I always thought they weren't particularly good value for money and you could often buy higher quality fittings at similar prices if you did your homework but they were often specified for clients who didn't know any better (and usually thought they were Italian because of the name) by lazy architects because they generally filled the gap between the bottom end and high end European brands.
