Impossible to lodge a building insurance claim on any of the various platforms

My home has suffered storm damage, and I am trying to lodge a building insurance claim. The call centre number is no longer published on various websites. The options are email, create a profile on the website, or register the claim on the app. I emailed the address, and received a link to the website. I tried to create a profile on the website, and despite carefully following the "number of special characters, number of letters etc" instructions, it would not allow me to create a profile. So I tried the app, which I have on my phone, but I can't find the "insurance" tile anywhere. I tried reaching out on Twitter, and haven't had a response.
