I understand your frustration, but I have some different thoughts about your comments.
1. Yes, shippers suck. But not very much. They are large corporate monsters and they can't help it.
2. Almost all sellers suck. That is, most sellers can't pack a piece of audio gear worth a damn. Wrapping a turntable into a trash bag and loosely packed in an oversize box 2/3 filled with packing peanuts is not good packing. And sellers need to understand that until the item I paid for arrives safely at my address AND I have unpacked and inspected the item, the sale is not completed.
If, as happened to the OP, the package arrives at the wrong address - not my (the buyers) problem. If it arrives damaged - not my fault. If it doesn't work (assuming that I'm an honest guy, like all of us here on A'gon 😁) - not my fault.
3. PayPal and I believe eBay require a seller to provide tracking information, purchase insurance and require a signature upon delivery. If not then the seller is required to reimburse the buyer within a fixed (short) amount of time following request for a refund, whether the seller is compensated by the shipper or not.
4. Ask the seller to provide you a photo of the unit, ready for shipping with the box open. If the packing is clearly deficient then void the sale and ask the seller for a refund if your payment has been processed. You don't need to accept crappy packing which almost always results in a damaged or inoperative product.
