As @-tony- says above, chances are that when you do call, you will be put through to the offshore call centre in which case you nights as well be talking to a brick wall for all the help they are likely to be. I fully expect you’ll get a ‘turn it off and on again’ followed by ‘leave it for 24 hours and I guarantee it work perfectly’ - hint: no it won’t!
So what I’d be tempted to do it to turn the hub off and disconnect it. Then call VM and say that you have no connection at all, you may be asked to switch the hub off and on again and tell them what lights are showing - just make something up. You may be told that ‘we can see the hub on the network and it is all working perfectly now’ in which case you will be assured that they are just lying and saying anything to get you off the phone - not, of course, that ever happens!
Ideally they’ll realise that the hub is obviously faulty and send a technician who should have a spare hub on the van. Ply them with tea and biscuits for the best chance of getting them to swop the hub out.
