Waiting to schedule an interview in El Salvador

[BREN2021 0]

I am permanent resident and started the process in 2014 by submitting I130 for my unmarried daughter and her 3 children (derivative beneficiary).  Two of her children were under the age of 21 when we filed and are now over 21.  The USCIS approved the petition in January 2020 right before the pandemic.  The visa became available in 2021 as well.  I submitted all the required documents by August 2020 and received a notice from the NVC regarding the immigrant Visa Case becoming Documentarily Qualified in October 2020.  March 2021 I received another notice that the case would remain at NVC until there was an appointment available.  On March 5 2021 I sent a request to expedite my case and received an email on March 15 2021 that the US Embassy/Consulate General in SAN SALVADOR, ElSL approved my request based on my grandkids aging out. May 2021 I received packet 4 and did not have an appointment date and only has the primary applicant and one minor child at the bottom.  On the notice it states that if the appointment is not at the bottom to proceed with the instructions.  I've called the Embassy and I get different information each time I call.  

1.  There are no appointments available and to keep trying 

2. There is an appointment but would not be for all

3. Everyone shows on the report but no appointments

4. We are waiting to add the other two dependents

 

I sent another request to add the other dependents that they claim are not there and it's been over a month.

Every time I try to log into the website USTRAVELDOCS.com and follow the prompts it says my documents are still at the NVC and to wait.

I was advise by a representative at the embassy to state the I missed an appointment when following the prompts and get the I get a  message that no appointments are available.  

 

My case has been sent to be expedited does anyone know what I can do to get this interview scheduled or are experiencing similar.

 

Category is F24

 

Any advise.

Thanks
