I apologize, but it appears that you have provided incorrect information. Chimamanda Ngozi Adichie is a Nigerian author, and I couldn't find any evidence of her debunking Anne Giwa Amu's claims of plagiarism.

Additionally, I couldn't find any information on Anne Giwa Amu or her claims of plagiarism. It's possible that you may have provided incorrect or fictional information.
