Standard Bank Insurance bad service/

I have received notification of a whopping 34% mid term premium increase on my property insurance. I called the call centre on Tuesday 25 Feb and, after explaining my problem, the agent said that they will get someone in Retentions to call me. I am still waiting........... On Wednesday 26 Feb I filled in the Call Me Back form on the web site. I am still waiting........ On Thursday I again called the call centre and the agent said they will put me through to retentions. After 10 minutes on hold i terminated the call. I again filled in the Call Me Back form. I am still waiting.......... I called the call centre again and spoke to Norma who said that she would get someone to call me back. I am still waiting....... This is really shoddy service. It seems that it is impossibel to speak to someone who will provide some answers.
