No, its very simple as you are most powerful as customer.
That useless BS empty statement of warranty denial is peddled by the illiterate service advisors who think they are gods because they work at the "komnee"
When you ask for that paper, they immediately know they are getting fired if they write it, ergo the answer would be
Janaab hum ko quality ka nahi pata aap ke haail ka, issi liye aisee baatein karte hain, laaye tel daaldete hain, aur book bhi staaamp kardete hain.
You as customer have to make sure to get your right.
Btw, speaking of name correction, specially on a degree, it happened to my uncle and all it took was 2 or days legwork, just needed govt issued proof of name which is NADRA in Pakistan as supporting evidence. (In his case it was an error by the univ)
If there is something screwed up long term in nadra like a spelling of ahmad vs ahmed and you never corrected it, thats a whole different scenario.
