You might consider checking your Spam and/or Junk folders for missing responses. Also, know that it often takes 72 – 96 hours for a response. If it has been more than 3 or 4 days, you can post your ticket number in the Sticky, ‘Tickets for Review’ in Account Issues.
You can also peruse the Sticky, ‘Not Getting Our Emails’, for information about CS responses.
Good luck.
