There are two of your from the same FO, filed within 3 days of one another, you've both completed your bio and are both waiting for your IL/next update at this point. The response you received from USCIS while related to your case, is not specific to your case alone.
Since your case was only filed about a month ago, I doubt if your congressional office agency liaison person will be too enthusiastic to initiate a follow up on your behalf at this point. But I don't want to discourage you from initiating the congressional case assistance at this point if you feel inclined to do so, miracles do happen.
