SRI CHARBHUJA ENTERPRISES - provide wrong screen guard and didn't change ask for extra money

I went for screen guard for Sumsung M**. He adjust some other that was not fit to the screen. I ask him then he said no no for this phone it is coming like that because of sensor all thing at that time i was getting late i came back. After that i see that was not fit and not look good. I went there and ask him than his behavior was so rude and saying yes i adjust some other and if you want give me half money then i will change after or else whatever you can do do it.
and he was saying *** rs is not that much amount how he can say they will give wrong product and say in this way.

This complaint is not about money this is for respect how he can talk in this way.
