Articleship -urgent

hi friends,

the articleshp problem pertains to my friend.

she had made a mistake in ITR during her first year of articleship training and her boss too approved it.

But on finding the faults she is now being continously screwed up for her errors. And the CA is also not ready to give her the articleship completion certificate...

what can be done?? will it be helpful if she complians  to the institute? suggest her.

Thank you
