New Hub 3 - can connect to hub, but not to internet

Hello, I have a new Hub 3 set up. I'm able to connect my devices to it but it's not connecting to the internet - on all devices it says connected, no internet access. The light is a solid white (more of a pinkish-white but I don't think it's red) power light at the bottom, no other lights. I've called Virgin Media on every help line and I can't reach a human. The only advice I've received is reset or turn it off and on again, which I've done several times and it's not fixed it. Can I get some actual help, ASAP? Alternatively can someone help me get a technician here to fix this, because the website is not letting me book it (it's not detecting any problems even though there are). Thank you.
