Hi all,
I've been viewing this thread for some time, and thought I might as well register to add my experience.
For us, the ghost call issue only started when a sales agent called us to upgrade our package, and increase our bandwidth. Ironically, this was the same rough time as others have mentioned (late autumn 2022).
Since then it's actually cost my wife over £400 in revenue, as she is a call operator that works from home: if she misses three calls on a shift (these calls drop her regular calls it seems, or come through at the same time), she is forced to log off and so every time this happens she loses earnings.
Virgin came out and moved us from a Hub 3 to a Hub 4, as the issue with the Hub 5 was well reported (as is seen in here), and it was fine for about a week or two but started again, for more lost earnings. She's since had to switch to using a mobile handset, which has dropped her rate but at least now she is making money and our rent is paid.
I'm not just here to vent, I'm here to be somewhat optimistic that the firmware update will work. I would imagine the reason for the delay is due to it affecting ALL hub types, so needs to be across the whole range.
The downside is that we're all still falling foul of this, the admins etc can't help us due to lack of information, and from a personal perspective we've been offered nothing by way of compensation for the lost earnings other than "info being sent to the relevant dept" courtesy of the international call centre.
I'll be watching this thread eagerly as the uncertainty of my wife's earnings is now affecting her mental wellbeing, and I won't allow VM to sidestep that responsibility.
