IMO, this a multi culprit FUHBAR as described
(1) SELLER
Seller chintzed it to a disgusting fault . Intuitively, it is just plain moronic for him to fail to properly pack up electronics with PROPER packing materials to both (a) adequately protect them from damage from shock, AND (b) brace them against internal damage from delivery mishandling. Negative feedback seems warranted in my opinion but onlyif you did not agree to ANY of his cheap boxing, or, he materially mislead you on this. Regardless, it should have been marked “FRAGILE “ and “ THIS SIDE UP”. etc. etc.
(2) BUYER
There is no mention of the unit having its own OEM packaging and OEM boxes that would’ve met (1).
If you agreed to this glaring omission at point of sale, then you assumed a big risk that it was a total unknown of packing adequacy , and this was entirely avoidable. Prior Seller feedback is a big indicator of Seller’s mindset and risk mitigation..,, a lack of it should have been a stark red flag.
I would never buy Pre-owned electronics for shipping without OEM packaging .,,there are many options out there with them to avoid this problem. On rare occasion that is entirely dependent on extensive Seller positive feedback, then I will take the considerable risks of DIY packing BUT with a clear written understanding and expectation to be done in a careful and diligent manner.
(3) UPS DELIVERY DUDE DUFUS
Chucking it about carelessly and casually was entirely avoidable on his part too. Good luck on getting anywhere on this because of this. FWIW, UPS is by far the WORST option by a country mile and I will always choose another option.
Was the shipping insured? If not, you are SOL.
TAKEAWAY
This is a regrettable joint sharing of risks and FUHBAR result in my view.
(a) You can try to get compensation from UPS , but good luck on that one.
(b) if you address it with Seller, he may offer something to avoid your negative feedback that will kill his future sales on AGON and other forums….. But I doubt that he will step up.
good luck ….
