Left the hub off overnight, and turned it back on this morning, and now it seems to be working fine (fingers crossed, touch wood)
However, I now can't find where to cancel the engineers visit (the confirmation emails just says 'To cancel or reschedule our visit, go to our appointment page to do so. - but the appointment 'link' doesn't go anywhere.)
On the VM Help page it talks about tracking engineer visits via the My Virgin Media app, but my phone is too old for this.
On the My Virgin Media site, under Order and Appointments, it just says I do not have any open orders.
Help please?
