FNB won't help me. Their customer service is the pits.

This my second review. I called FNB again today. I just spent R100 of my airtime. On hold. Firstly I have an FNB sim card but the call was not free. I called ***. The shares investor department. I explained my story again. I spoke to a consultant who said it's best he directs me to the consultants who know my case (Angela and Bessie) I know the managers name is Ndumiso Mosala or Mohlala. I was transferred to Angela. I was on hold from 16:04 till 16:49 when my airtime finished. No one wants to help me. What should I do for FNB to give me my money. By the time I get through all these calls I would have spent more money on airtime than what they owe me at this point I just want to close the account and get my money.
