Standard Bank Non-responsive call centre.

I had burglary at my home last Thursday. Have tried to contact Standard Bank Insurance a number of times since Friday morning. There is no response, the phone just rings and times out. As I am a Private Bank client, I called the Private Bank call centre. After explaining the matter, the call centre agent forwarded the call to the Insurance department. The phone just rang as before. I could not get a reference number as the call did not revert to the original number.
