Congratulations that everything went well in the end.
I got a call here in Germany from UPS today, that i should send them infos about whats in the package, since the customs won't believe that it's only 11$ as it is labeled. Never had something like this before whenever i got something per dhl from China to Germany, such small things normally just went through without checking them. Will see how it goes, since i would have to pay import taxes on things over ~29$. Not sure about what UPS is doing there ^^
I don't know what the problem is with UPS but they sure do seem to have it out for vape packages lately. It just seems like they are doing everything possible to harass vendors and purchasers no matter where they live in the world. I'm sorry you are having a hard time and I hope that they release your package to you.
