Registering at the Gemeente part 1

Gemeente means municipality in Dutch. Slovenia became a part of the EU in 2004, and joined the big union with workers movement and portability, and everything got so much easier, and you can get a lot of information about that on the EU portamobility site here.
Well, don't believe that it's all that simple. The workers market in Holland only opened in May 2007 and several other countries of western Europe are still requiring a work permit if you want to work.
But ok, I want to work in Holland, and now I can. Only one small detail. If you want to work in Holland, you must be insured. Ok, I am insured in Slovenia, and by having an EU health card, I get the same rights in other countries as I have in Slovenia, no?
It's a bit hard to find an answer to that question. EURES - The European Job Mobility Portal is only giving information about moving to another country. Well, I am still staying in Slovenia, thanks, I just want to work in Holland, when I am in Holland.
So I asked around. The employer is only leaving an option of a dutch insurance company and I couldn't find a solution for my case. Maybe my case is a bit dubious, but for example, I come to Holland for 2 months of season work, picking up the strawberries, or whatever. For staying under 3 months, I don't have to register at the municipality, but what about the insurance? I couldn't get any answer. Maybe the only place where they might give me a hint would be some organization specialized in providing foreign workers to Dutch working market. I guess there are many for Polish workers, but for sure none for Slovenian.
So, there it will have to be. Dutch health insurance, as an addition to my Slovene one. But another problem, in order to get a dutch health insurance, I need to be registered at an address in Holland. So now I have to register although I travel to Slovenia at least every 3 months.
So in August, when we got back from Slovenia, I decided to register. It said on their web page, that one has to register in 5 days after the arrival. A bit strange, what if I decide to stay after 2 months. But whatever, I went to the municipality and asked at the desk, where can I register. They told me, that I need to make an appointment if I am moving from abroad. Again an appointment, I thought, nothing happends in this country without an appointment.
"Ok, let's make an appointment."
"No, no, no," he said at the desk: "we can't make an appointment here, you have to call this number and make an appointment."
And he gave me a phone number. How ridiculous, I am standing at the desk, and he can't make an appointment for me. Why doesn't he call that number? Huh.
So I went home and I called. The person who picked up the phone didn't make an appointment for me, but only took my data and asked for my phone number.
"We will call you back."
Phhhhhhrrrrrrrr. I have to register in 5 days from my arrival and I need to have a phone number. If you are moving to Holland, first thing you need to do is buy a prepaid phone card, because everything will go over that phone. I learned much faster how to say my phone number in dutch than how to spell my name (btw, they never wait for the spelling of your name, they just write something and then you have problems when your name is not matching with the one on the appointment schedule).
I was called back the next day and was told to come next week on 22. of august at 10AM. I need passport, a birth certificate and a permit for moving in a house where I am going to live by a house owner.
