See this tale of woe
The current VM installation process is badly managed when things aren’t straightforward and cable re-pulls are needed. So dont bother chasing it. Just let the installation play out. Do nothing. You will pay nothing (£0) until a VM connection is actually installed and activated. And even from then (if it gets that far) you have 14 days in which to cancel - again with no costs. Or keep it if you like it after those 14 days
In the meantime, can you connect her to OR, Sky, BT etc - or to a 4G/5G service - perhaps on a 30-day contract? Three have a 30day 4G unlimited package for ~£20. If so, do it now and just let the VM install run its course. As said, you will pay nothing until VM's service is installed and operational. When it finally happens, you have 14 days in which to cancel it at no cost to yourself and keep the other service. Or, if VM is working to your satisfaction, keep it and cancel the other service (hence better if you took a 30-day contract).
FYI - Re. VM’s recent installation issues - see John’s excellent précis of the situation in message 18 here…https://community.virginmedia.com/t5/QuickStart-set-up-and/Multiple-Failed-Installations-zero-commun...
