Case Was Reopened For Reconsideration after RFE evidence was never acknowledged by USCIS

[Ash2019 0]

Hey everyone! My family submitted an i-130 form in JUNE 2013. Received an RFE IN MARCH 2020. Responded in MAY 2020 but we never received a notice that they received our evidence. I made an electronic inquiry asking about it and stating we never received a response to our RFE and this was their reply: "October 30, 2020 Case Was Reopened For Reconsideration On October 30, 2020, we reopened your Form I-130, Petition for Alien Relative, and are reconsidering our earlier decision. We sent you a notice that describes how we will process your case" AND "The status of this service request is: Recently, you or your representative contacted U.S. Citizenship and Immigration Services (USCIS) about your Form I-130, Petition for Alien Relative. We are still reviewing your case. We will mail you a notice when we make a decision" I called them to verify the info and they said the case was never closed or denied. Just to respond to the new notice in the mail. Anyone have a similar situation happen? Our priority date is now current after all these years.  Any advice on what could of happened or the meaning of the notice? Thanks in advance!
