Query BVR66

I did an application in November 2017 to have my surname reinstated back to what it was originally. I have gone in personally to Randburg Home Affairs twice to follow up if the application was processed. I have written to Home affairs on the website where it says submit a query. I have tried the ********** 190 number and it is not available/working, I have also emailed the District Manager Johannesburg and the Office Manager at Randburg. I have sent an email to ********** There has been no response! My query is very urgent, I need to have my passport reissued with the correct surname as I travel at the end of March. What does a person have to do to get a response!
