Poor Service As A whole

I was assigned an agent to help me with a reversal I had waited 2 week for and still was not coming through. The agent called once and said she will keep me updated that was last week Friday, I emailed her and she doesn't even reply to my emails. This is the third week I'm waiting for my reversal, I'm a student and had to go through my exams without any food today I need money to go home and still FNB is not doing the reversal
