I can see that you have been speaking with my colleague Zoie in regards to these issues via PM. I can see that she's offered to contact the Area Field Manager to find out what can be done to resolve this issue.
She is off shift today, however I will catch up with her next week to see what the Area Field Manager advised. As soon as we have any updates for you, we will let you know.
thanks for messaging with me, please let us know how your visit goes, if anything changes or if you want to view your appointment you can do so on your My Virgin Media account on the Help tab > Oders and appointments,
When they have been let me know and I can assist you further with the complaint you have raised with myself.
