No "real pro" vendors give you the dcn when you purchase. Those are for us not you. They are not tracking. But this vendor is doing you wrong 100%. If he has the DCN then he should tell you he has it and provide it to you... not some bullshit excuse like the one you are telling us about. Who is this vendor? How long ago was your order purchased? How was it shipped? What was the item? All of this matters. Also don't let it auto finalize. And don't offer him 50 more days or anything like that. That is silly. Either he can prove it was delivered or you get a refund. Simple as that. All those questions matter and depending on those I could give you a better explanation. Bottom line is if he can provide SR a DCN then he wins the case. As it should be. If he can't...then you win. That is the point of the DCN. There is NO GOOD excuse. You either have it or you don't. The odds of him having another order in your zip code are about 100000 to1. So your safe there. It would have to be an order at the same time as your too. Please answer those questions and I can help you more. Sorry this is happening to you. It sucks that your with out BTC and product. And you contacted the vendor and basically got a nothing he can do response.
