No Response Following Repeated Attempts to Contact

Following an upgrade to Private Banking, 2 weeks ago I left a voice message for my Banker to contact me regarding some issues on my account - no response. 10 days ago, I mailed my Banker with the same issue - no response. Last week I called my Banker, couldn't get her but left another message with another Banker stressing that she return my attempts to contact her - no response. Yesterday morning I logged a complaint on the FNB website and await their response. The website advises contact within 24hrs - still no response. I guess I must just live with this pathetic service then.
