Error on certificate of citizenship

[Elmaelt]

Hi

I would appreciate your advice on this, specifically if you have been through a similar situation.
Upon receiving my payment letter I noted a mistake, my country of birth is incorrect! Other information such as my name, date of birth, nationality and address are all correct ! I have sent them a query to notify them with the issue and paid the certificate amount. I later received a reply to the query that the issue was directed to the team who deals with this .

I then attended the ceremony but when the certificate itself arrived it showed the same mistake ( not fixed)

I heard any wrong detail in the certificate will cause issues when applying for passport! Therefore I have returned my certificate with a cover letter explaining the mistake.

Then is now more than two month since I have returned the certificate and I have not heard anything . I have already sent a query on the portal ( a month now ) and there is no response! The only thing I have noticed is my citizenship application status changed from application completed many month ago to in progress again ( a month ago)
I am not sure what to do anymore?

Is there ever a number to contact? Should I actually just go physically to their office! It’s becoming very frustrating at this stage
