Awaiting Feedback

I have been desperately seeking feedback for my PMB application made on the 6th of March 2018. Every time I follow up, I'm told the application is with a case manager. At some point a team leader Ella Letlole, promised to follow up and give feedback, she gave me an incorrect direct line, reads my mails and never responds, at some point I even pleaded with her to direct me to her line manager if she is unable to get the feedback for me. I don't know insensitive can people like Ella be, its like I'm at her mercy for a mere outcome. Can someone please come to my rescue.
