never said you were. but to address the things you brought up
1. just about every artist does free touch ups, usually you get them a month after you get it done. it's all dependent on your bodies healing time though.
2. 2000 nok for that tattoo wouldn't ever happen, at least in the US. in USD, that's about $320. you said it was an hour long tattoo. 699 nok is about $110. for an hour long tattoo, you actually got overcharged, at least if you got that in the US you would have. for an hour of work, that should have been about a $90, including tip.
3. no, you cannot tell them that line is "ugly" and they'll fix it. that line is there permanently. all they can do is add to the line, which will make it thicker and make the overall tattoo look heavier on that one side
