Can I reclaim the broken part, that was changed, from Apple store?

Question

Hello All,
I am an apple customer since 11 years and for the first time, I am sad to say, I had the worst experience at the Apple Store Fiordaliso in Milan, Italy.
I have had problems with my screen (zig-zag and then at restart white screen), which was not exactly the best timing in the middle of Fashion Week work etc... so I took the computer to the apple store Fiordaliso to check it out. The first guy (lets call him Mario) runs a diagnostic on it which looks like the attached image below, where I saw that the RAM the HDD the CHARGING and maybe THE BATTERY might have issues.
Then Mario tells me its the motherboard. Hm... but not according to the diagnostics. So when he leaves I catch another guy (call him Luigi) and he runs the diagnosics again, comes up with the same result and tells me the RAM is fine, its just not apple RAM but accepted, the HDD might be the issue and probably its electricity supply. I ask him if he is sure if its not the motherboard, and Luigi says, that no, he doesnt think so. his solution would have costed me 38€ plus tax. What Mario told me costed 487€... I liked Luigi more...
Anyway, My computer was taken in by Luigi for repair. But later in the evening Mario calls me and says he has detected the issue and will change the motherboard. I asked him about what happened with Luigi's diagnosis??? He says he ran a test again and its the motherboard. Having no choice, since I needed the computer ASAP, I told him okay, but I want the broken motherboard back! He says ok and hangs up.
Today I went to the Apple Store Fiordaliso to pick up the computer. And Mario came out, gave me the computer and the bil but no broken part. When I asked him where is it, he started to say this and that, that APPLE CANT GIVE BACK THE BROKEN PIECE BECAUSE IT IS THEIR POLICY. After a long italian (means pointless) argument, Mario tells me that he cn change the parts back as they were NOW and give me back the computer as it was. I said, no I simply want the piece, thats all. I have asked for the manager, who told me the same thing and repeated it about 10 times. eventually I told them "okay, guys this is weird, just show me the piece then and I leave". By then MArio has disappeared entirelly, not to be seen again and the manager left me as well, waiting for about 30 minutes, then I caught him when he finally reappeared for a second. He called a technician (at this point I didnt believe even their questions nor gender). This technician (lets call him Benito) starts very smooth, repeats the EXACT same sentences I have heard so far until the point when he said, I cant have the broken part back because it is already in China for refurbishing. I asked him, how is that possible, since Mario told me only an hour before that he can change it back right now, no exlanation just loud talks and HE is getting agressive, to the point that he reaches over the table, takes my computer away and says, that I have two options: I pay and leave with the co puter or the computer stays. I kind lost it right there and took the computer back, when a civil policeman standing behid us and watching the story, intervened. Luckily he found it weird hiself, but of course he didnt make much difference at the end. I have agreed to pay the 478€ and tried to force some kind of an agreement out of the italians, but no use. I needed my computer back desperately...
As a last word the policeman forced Benito to at least give me some point which I could prove to myself that the switch has been done. Benito said, if my home wireless network does not recognises my computer then they have done they job properly and the motherboard has been changed.
Now I am home. My home internet connected automatically...
Anyone has any idea what can I do about it now??? How can I find out what are (were) the original parts of my computer? Can or would Apple help me with this issue?? I have never had any problems with Apple but this was extreme and I feel totally just laughed in the face.
Thanks for the help in advance
cheers
Adam

You will have to restore the new iPhone to erase all the data that is still on it. Usually, the seller does this before the transaction. But after you restore the iPhone, you will be able to use it as if you bought it from apple that same day.
Try arranging a meeting with the seller before paying though, just to be sure the thing works fine. If it works fine for him, it will work just as good for you.
