Just so you know, I reviewed all of the feedback for the Seller under discussion. He has had very few negatives during his career on e-Bay BUT... I would agree with you that his people skills leave a lot to be desired in his responses to those complaints. I will not attempt to justify the delay in shipping out the item to you. That should not have happened and you were certainly owed a reasonable explanation for the delay since you apparently did nothing to cause it.
The problem with the address label seems to be a different story. Was it the tape he used or was the issue with the ink? How would the Seller have known that would happen and what would be the point in him knowingly create a label that would become difficult to read?
In spite of your negative feelings toward this man, he should be informed about the label problem so it does not get repeated, if only for the sake of some other Buyer.
Only you can decide whether negative feedback is truly justified because this happened to you.. not me.. not anyone else ...and you have all the details.
Moving on from that issue.........
On a general note, I am disappointed that some of the replies attempt to vilify e-Bay. If you go to the Mall of the America's and have a bad experience with one store, does that mean the entire Mall should be boycotted? Isn't a Mall just a huge building that rents out space to individual Vendors? Isn't e-Bay basically the same thing but without the bricks and mortar?
Just like e-Bay, the owners of the Mall have rules that the tenants must adhere to and when there is a clear breach of those rules on an ongoing basis, the Mall owners have the right to void the contract and eject that Vendor.
Mall owners do not employ staff to investigate the source of the goods being sold in the various stores to see if they were stolen or purchased legitimately. Such a notion is absurd and so is this libellous accusation that e-Bay knowingly "fences" stolen goods.
Realistically, it is next to impossible for a retailer to make every single customer happy 100 percent of the time. The best that any retailer can do is to try and right the perceived wrong. The Seller in question has attempted to do just that on several occasions but his choice of words in his replies leave a lot to be desired. Most e-Bay Sellers work very hard to keep their feedback rating above the 96 percent mark over the course of a year because it hurts them financially when they don't.
It's too bad that this happened and I agree that better communication could have avoided much of it. At least you ended up with the part you wanted so badly.
