While I don't order from Vapsourcing I think a threat to hack endears you to no one, nor would any legitimate hacker like, announce it.
Also if this is how you react to a simple ordering issue, I wonder how you handle: roadwork, traffic, your friend telling you they didn't like the TV show you picked etc. I do not know what "hacking for a living" quite means, but if it's sanctioned, I cannot imagine a person IN that field proudly announcing it, and if it's unsanctioned well, same goes. Etc.
I mean, good luck with your order but also, chill already. Also, even if you don't get your order over the holidays, well most vendors do announce that fact (I don't know if Vapsourcing did, but probably). So, if you didn't read it that's kind of on you.
If Vapesourcing did indeed mess up your order and it's from before the holiday I would think you will have a legitimate gripe, in which case work with them until it is managed to your satisfaction, then never order from them again, it's that simple.
If you think you are the first and only person to run into a vendor with a problem, you are not. I think we all have our list of "Do not buy from," folks, and mine is Gearbest. It would take a cold day in hell for ME to order from them again, while tons of folks like them, use them, and they often have good pricing. Just chill, whatever happens making strange threats is just not the way to go. If you want the vape stores to be professional, do that too.
My favorite China vendors are fasttech and buybest BOTH very professional with good prices. Just a FYI for in the future.
