Ya some vendors are cranky and overworked. :-)For the record, I've had three mistaken orders so far from different vendors , so they mix up packs for sure. . . I ordered 10g of hash And got 10 speed pills instead. Another was MDMA and got coke instead. The last was an order of weed and got meth hahaha. So, shit happens. BUT I got a reship on them all and also got to keep the first orders so I was ahead. Your vendor should listen, but as a last resort you could need to send him a link to an anonymous image board and post a pict of your mistaken order . He should see the pict and recognize his packaging and see the error. Also., there has to be another customer with your order saying the same thing?  He thinks you are scamming him and you can't blame him as it happens a lot and they must be fed up,. I think if the vendor sees the image posted of his package and all the work you did you prove yur case, he should listen. It sux the you need proof though. Kinda snotty vendor though . He must be small time and struggling for dimes and pennies if he can't do it without breaking his bank. Jeese.I hope this helps. Scrub any images you post first so there is no data in the image ( save as bmp, then back to jpg). Damn. Too bad it wasn't in your favor. :-(   --->!THe best option is dispute resolution. Don't release the funds to him. Click resolution . He won't get paid until he corrects the error. This is what you are suppose to do .
