Unacceptable service

I am trying to sort out a claim. I have spoken to over 5 people. The only person who is helpful is the assessor from standard bank. I have left 7 messages on a voicemail for the person, apparently the only person who can help me, to call me back. I have not had one call from her. I get put on hold for over 4 minutes trying to contact anybody who can help. I spent 30 minutes on the phone today and still had no success at the end of that call. Unacceptable service for YOUR clients I can see why people are moving banks
