The Curse Of A Double Surname

As you may know, Spanish people have two surnames.
It always consists of the first surname of the father and the second surname of the mother (So in the end, the mother's surname gets lost when their grandchildren are born)

And what happens if a Spaniard comes to Austria (specifically: STYRIA)?
RIGHT, people totally distort the name.
A wonderful surname like (in my case) Catalá Salvá (pronounced: Ca - ta - laa Sal-vaa) becomes Catöla Sölva, Kátala Sálva, Catala Salta and other absolutely horrendous variations. In order to not get confused, people here put a hyphen between the names and/or leave off the accents.

Or, what if a Spaniard marries an austrian woman?
In Austria, the woman takes the  man's whole surname and in Spain she keeps her girl name.
So, if they have children, their surname in Austria is Catalá Salvá and in Spain it is Catalá Kotzbeck. Waaay to ruin it. But noone actually uses Kotzbeck anymore, my mother uses Catalá Salvá everytime. (Seriously who wants to be called Kotzbeck? Sorry Grampa and Grandma)

Can you imagine what it is like, sitting in a new class with new teachers and having to explain your name to every single one of them?
"Sálva Alba Cátla?"
"No professor it's Alba Catalá Salvá "
"Oh but Salva is your second name, right?"
"Noo professor it's my second surname"
"Oh, why's that?"
" 'Cause it's spanish"
"OOhhh okay...but the hyphen's missing"
"Nooo professor there's no hyphen"
"Oh...well, I'll put a hyphen between the names so I don't get confused"

OR, what it's like to get your school photos taken and then recieve them just to find your name "Salva Catalá" on every single one of them? And then also in the years book??
Y'know, I get it, it's complicated. But I don't understand how someone can confuse a name with a surname? And I'm not only talking about me, I'm also talking about my brother. He has a wonderful, simple name that everyone knows: Rafael. You know what they put on the photos this year? "Salva Catalá" NOW HOW THE F*CK COULD SOMEONE FORGET "RAFAEL", HOW? And then there are some classmates with names like "Christina Zoe Lara Maria Krwopealjdfntsa" (<- only an example) AND THEY PUT IN EVERY SINGLE NAME. AND WRITE IT PERFECTLY RIGHT.

*huff huff* Okay I calmed down. Sorry.

I really am sad because I think our name is no that hard to understand...I get that maybe some people misronounce it or misspell it but what I don't understand is that they can't distinguish the name and the surname...
Actually, if you have the name on a paper right before your eyes, why is it so hard to totally confuse it?
My mother reflexively corrects every person if they mispronounce her name, every time until one day they hopefully get it...(Sounds a little bit rude sometimes but YOU GO MOM. I also picked up that habit xD)
