How to deal with 2 NVC inquiries expedited?

[SamiTay 0]

So, my spouse (US citizen) applied I-130s for:

1. Me (Spouse) (IR1) \[Priority Date is Aug 2021\]
2. 2 year old child (IR2) \[Priority Date is Jan 2023\]

Both cases are documentarily accepted as well by NVC, but since both were applied in different timelines, we wrote to NVC asking them to merge/combine our cases so that they can be processed together.  

Just yesterday, we got a reply back from NVC which is that they sent the request for expedite processing to embassy: "The National Visa Center (NVC) will send your request for expedited processing to the U.S. Embassy or Consulate.  
..."

 

And today, we got another reply to the same inquiry saying, "If you want to request that we expedite this case, please provide us with more information. Please send your request with the supporting documentation (such as medical records, a letter from a medical doctor, or deployment orders) to [NVCexpedite@state.gov](mailto:NVCexpedite@state.gov).

When we receive this information, we will send your request to the appropriate U.S. Embassy or Consulate for review.  
Please note that only the U.S. Embassy or Consulate has the ability to approve or deny expedite requests."

Now, my question is, is the latest reply the one I should reply to? Or should I wait for the embassy since NVC said that it will send our case to the embassy/consulate? What would be the best decision to take here?

Could it be that 2 representatives replied to the same inquiry?

 

My primary concern is NOT the expedite, but our cases being processed together. Please advise.
