Why are you mean like that? Everyone can make a mistake.
Sure, but if they rush things and don't value your Time, why should they get away with it ?
It's been a hell of 3 Weeks for me, so sure, my Patience is definitively not in the best State. Let alone all the small Deals here and there full of unreliable People.
First a Package from UK delivered, marked as delivered, stolen 3 minutes later by the same UPS Guy that let it in front of my door without Signature. Package marked as delivered forever. Then they start claiming some Customs and Processing Fees, even though I paid everything via eBay Checkout and it was written as such ! Seller was very friendly and helpful, but UPS got hammered. You make me waste 3 Days like that for a Fee that you pull out of your rear End ?
Then a Pallet from NL delivered, marked as delivered, just ... to the WRONG ADDRESS ! Seller was helpful, NL freight was helpful, DK freight was full of ****. First one Guy processes the Issue, confirms they delivered to the wrong Address. Then nothing happens for 3 Days. Then he goes on Holiday, somebody else takes over and when I try to follow-up they just say that "Pallet was delivered". So from the top ... once again. Follow-up with 3 different Companies (DK Freight, NL Freight, NL Seller). Finally after 3.5 Weeks I got the Pallet delivered yesterday ! And for sure as hell, while I can be somewhat understanding to the Driver (everybody makes Mistakes, maybe was tired, maybe his Kids were sick, whatever), the way it was handled by the Company (lack of follow-up, lack of Handover, lack of Control over what they do, ...) was absolutely awful and granted a negative Review. Let alone that the Pallet was only delivered to me after the wrong Recipient contacted them !
Making Mistakes is human. But the Way they handle it makes all the Difference.
Compare this level of "Service" with what I had happen to me a couple of Months ago: from eBay US I bought some AMD Radeon Pro V620 GPUs. Delivery Note indicated 12 GPUs delivered together with their respective Serial Number. 2 Days delivery with DHL. I could only see 9 GPUs in the Package. I contact Seller via eBay Message stating that and list the missing 3 Serial Numbers. Seller IMMEDIATELY has some internal Talks, find the missing 3 GPUs, excuses themselves for the Error within 1 Hour, package them properly and sends them via DHL (1 or 2 Day Delivery DDP / Zero Value, i.e. no Custom Fees extra to pay). A World of Difference ! Seller was feeling bad and a bit embarassed, but to be honest, the Way that it was handled, was top Notch. Granted it was easier for them because I gave them the list of S/N to look for and they immediately found them on a Table or something (maybe a stroke of Luck too !). But this is what a good, honest, friendly and cooperative Seller looks like

Sellers that just hide behind some Rules to justify their lazyness and lack of Control / double-checking, meh
