Slow down and relax please. I understand your concern. You are correct in that I can do nothing to make your order get changed or refunded or get to you faster.
If you hang out in the forum for any length of time you will quickly see that this is not a bunch of "bots" or a small handful of employees "faking" it. Seriously, just hang around awhile, there are too many legitimate people placing info about their own successful grows with seeds from this site.
Also, something to keep in mind, this is not like most regular businesses. maybe it can't be treated like a "real" business. It is very likely that your order is to a place that receipt of such a product is considered illegal, and so many things will not be at all like other businesses. I honestly have no idea how things work in the Netherlands, and they sure are not going to talk about it in a public forum on the internet. All I can say for sure, is in over 2 years of working with them, and helping countless numbers of people grow the product they have received, I have no question in my mind that they are legit and will honor their seed guarantees if you have patience and keep working with them.
As far as the 24 hours thing, I have seen numerous people complain about not getting a response in 24 hours. I know they are not "open" on the weekends, or so it seems. I don't know why some people are very happy with the response time from them and some are not. I'll send a note about it up the chain, as well as sending a note about your specific complaint and hopefully that will get someone to get back to you soon, that is about the best I can do. Don't forget there is a likely big time difference and give it a bit more time.
