gyakutai, grow up. Seriously. At least you can afford going abroad, some people don't have rich parents or job, so they can't. Many people skip Poland, but when someone really likes the band they try to go to their live abroad, there is nothing for free, if you want something you should be the one trying to get it, no one will get it for you.
I'm pretty sure you're talking about Astan and Nega, because I saw your comments on Facebook, but they're probably busy with something else, maybe planning another lives, so they don't know if they will be able to do the live in Italy? Everything is a matter of timing and money. Maybe Italy is too far or not enough people would come to the live or they simply don't know, so they don't want to take the risk? Managing a tour isn't a simple thing, you need to pay for the band's transport, they usually travel with their staff, so you need to pay for transport of many people. Think about how much do you spend on the transport just for yourself and then think how much the transport of so many people would cost. They also need a hotel room, which isn't cheap either. They need to eat, someone has to take care of them during their foreign tour (language stuff, sometimes the bands want to go sightseeing as well). They need to get to another country on time, so if it's not on their way to another place it may be difficult to arrange anything. A good club is needed as well, sometimes the dates are taken. It's a lot of work and a lot of money, not fun on a playground in the sandbox.
By the way, Astan hasn't even started sending invoices to people who ordered their tickets for the Utrecht live, so they're probably busy with something else. Cologne almost sold out, maybe they want to do this first, because it's a lot of information to manage. I don't know what's the reason of it, but they aren't discriminating Italians, your booker isn't the only person they didn't reply to. And yes, they aren't coming to Poland, so I have to go to another country TOO.
If your attitude towards foreigners is like this I'm not surprised you're getting insulted by others. I was in Berlin once and people were really nice to me, also when foreigners come to Poland everyone tries to help them if they ask for it... but if they acted like idiots everyone WOULD talk behind their backs, it would be the same with people from our country though. No one likes annoying people. Maybe you're loud or do something not acceptable in their culture or it's your imagination and no one treats you bad in fact. V-kei fans can be really aggressive on the lives, towards everyone, because they HAVE TO touch their hawt yummies.
