Gramarly.com review: I am still waiting to receive feedback on my questions and remarks

This program checks errors in writing, and it has flaged punctuation as incorrect when other sources clearer state as correct. The sources I am referring as showing correctly are, "A Pocket Style Manual" by Diana Hacker; The Chicago Manual of Style in writing"; "The Elements of Style" by William Strunk Jr. As of this date, I am still waiting to receive feedback on my questions and remarks.
