Unprofessional

Have been with Dashfibre since 2020. Never had any issues. Started experiencing issues with my Wi-Fi and tried reaching out for the last 3 weeks to discover they are no longer in business. No way of contacting them. Don’t know what to do. Have been paying them every month and have received no comms to say they are migrating me or that they no longer in business. Have tried contacting other isps hoping someone can help but nothing so far. Unsure what to do now…
