I sent IRCC a message through Epost two days ago asking when I am gonna have my eligibility interview. Today an officer replied the message to me and told me they are waiting for me to submitted the files they requested on May 27th, which I already submitted on the same day. I am so glad Epost has an activity record. And I sent the documents along with the activity record showing IRCC officer opened my submitted correction on June 8th.
Basically, they told me if I don't send in my files I'll not get the eligibility interview. I think for your case, it is worth to send an message to IRCC as well asking why you haven't got the interview scheduled. You never know someone may forgets to update your file.
