I know it's utterly pointless but it helps me to vent, just feel so powerless!
If the complaint is about a fault in the area, which VM is acknowledging is present, then there is not too much else you can do other than wait for it to be fixed.
If you are experiencing a 'total loss of service', make sure you have registered that as such by phoning it in to VM to report the TLS.
You should be eligible for compensation for a TLS but the scheme does not cover intermittent faults if that is what VM is trying to claim the issue is as a means to avoid paying
