not getting back

I recently was employed by FNB till my temination occured. I requested for a correction on my certificate of service from lucrecia de klerk on the 23Jan 2015 and again on 2 Feb I tried calling but with no luck. I than contacted stephany bentley on 5 Feb2015 and she asked that I forward it to her on a email and she will forward to the relevant person. Today is the 23feb 2015 and I still had no respnse. It is affecting my current job application. Please get those people to work.
