Onsite technical assistance needed in Melbourne Australia.

Just spent 50 minutes on phone support, to get to a point where an onsite tech is required. The numbers provided were for America. When I asked for Australian companies/numbers to call, they eventually came back with Australian numbers that either werent connected or went to another company that was unrelated and both numbers were interstate. Issue: Last night the chime Pro a/c socket was switched off. But has since been switched back on. 3 out of 4 other ring devices were connected to the chime pro. But since switching back on, can't get Chime Pro to reconnect, even after factory default reset. Have tried switching all other Ring devices to run off home network, rather than the Chime Pro, but they're all failing to connect to home network, stating poor network make sure your device is close to router etc. Now all but one device are not connecting and offline. I have internet. Have other devices (work and personal laptop) connected and working per normal. Tried resetting modem – no change. Ring devices only a metre from router. Tried removing Chime Pro, and re-adding to no avail. Just looking for efficient, effective technical support within Australia. You have read to here.
