so... your teacher purposely dropped your guitar and the store staff purposely give you wrong strings. 
yes, he purposely dropped my guitar. i didn't know he did it on purpose until half a year later i confronted him about it and he said he doesn't know what i am talking about. because the vietnamese words for guitar is cay dan and also cay don. they are the same thing but he pretends to not know what cay dan when i told other he dropped my guitar. he said he doesn't know what cay dan is then later he said oh cay don.
After a few minutes later, he said he put it in a bag before he dropped it. that is true bullshit there. because on the day that he dropped my guitar was the only day where he told me not to put it in a bag so i didn't put it in a bag. so we left for lunch, then we come back and as he was playing his keyboard, he purposely dropped my guitar face down and ruin the strings. he quickly pick it up and put it back against the wall. if he put it in a bag, it would look different because the bag is black and the guitar is brown.
i remember last december i asked him long have he came to america and he said he came here since 1993. then in late january of this year, he told other students and other staffs there that he came here 10 years already. i thought he was being generous and modest that he lied that he came here 10 years already when he actually he came here for 20 years.
so i asked him to be sure and he said he came here for 20 years. so i asked him i am not sure which is true? 10 or 20 years? then he said that he lied to me and that he actually came here 10 years only. then he went on and say that he lied but he didn't harm anybody though and he told me not to tell others that he lied to me that he came here for 20 years.
i agree with him that he didn't harm anybody from lying and its his business so i didn't bother telling other students. i told my mom about it and i said its his business.
again 6 months later, i found out he purposely dropped my guitar and ruined the strings that i gave him the glare for hours until the class ended and i left home that day didn't bother coming to his class anymore. one of his students try to lure me to come to his class to practice but i refuse.
take photos of the guitar and show me, also hold down the thickest string at the first fret and the last fret at the same time. What size gap is there at the 12th fret between the bottom of the string and top of the fret?
not sure if i should bother with it since i don't want to deal with this guitar with sharp strings anymore.
