Disgusting service from Standard Bank Insurance

My geyser burst on 6 June. Trying to get hold of anyone from Standard Bank insurance is a nightmare. I was on hold for 25 minutes, before I gave up. I logged a claim online. By 17 June, I have still not heard back from the company, except to say that they have received my claim. I had to get a plumber in to fix it. I sent photos, videos and the invoice. I have sent numerous emails. Still no response. Disgusting service.
