I App**** for an expungement and now is the 8th month waiting

I App**** for an expungement and now is the 8th month waiting. I went there at 271 Bothongo Plaza Pretoria and I was told to leave an EMAIL address and I did as told. Still today no one is sending me my certificate. Was given ref no 7311/23 for the issuing of certificate but no one is helping.
