Mirrors climbing on deep hardware understanding (keys)

Let's start from the beginning. I got my DZ in august and the keyboard started in october to not write keys like k and j one time on many... the problem got worse (at first it was just one key) and I sent it to assistance, got it back with a new keyboard. Now the volume up key is broken, it doesn't do anything.
May I found something to tell HTC that the problem may be relate to the other to get a replacement?? I don't want to send my phone back to HTC every four-five months...
They said they couldn't cause I sent the phone for the first time more than a year ago... then I got them to understand that it wasn't possible cause I have had the phone for less than a year. Then they explained something in an italian that was worse than my russian, very bad...
Can someone help me? is there some connections between all hard keys? If I can show them that I understand how phone works they may take me more seriously... Unluckily it isn't like in the US where they give you a sensation...

The volume up and down are built into the harddrive. The keyboard keys are conected to the hard drive via flex cable. They more than likley are separate issues

If you have a one year warranty and your phone is less than a year old and it dosent fully work you shouldn't have any issues sending it in. Maybe warranty means something different where you live but if my volume key didn't work I would be able to get a replacement

Hey, it's Italy!! Here we've two years warranty, but no replacement, just repair... Everytime this phone breaks I have to send it away for a week, and if I could have a replacement I'd prefer... Not so funny to have to unroot e reroot every time... And my DZ has many scratches...

Whoa! The terrible translation made my day! Mirrors climbing on deep hardware understanding lol! No offense to the OP at all. This was too funny! There was another one by a Chinese member the other day that was even better: http://xdaforums.com/showthread.php?t=1607345 Google's translator needs some serious work!

Nono yeah, as a matter of fact I translated it by myself, I thought that mirror climbing was an english espression too. Here in Italy means trying to find reasons to support something when you know it's very difficult or even impossible, like mirrors climbing. The second part meant that my reasons had to be related to hardware, so I needed someone skilled enought to be able to find a connection between volume and keyboard, should have been deep understanding of hardware, but I'd modified the title so it was wrogn at the end...
Sorry

Ps I'm sure I've read 'mirror climbing' in english somewhere

Edit: checked and it's used in Italian also with these English words, so I've seen it on an Italian site written in English... You should thank me now if you come to Italy, you'll be able to use a new sentence
