Activating Volt benefits

Good morning :)

A few weeks ago, my service with Virgin Broadband started and early last week I got an email from O2 (who I have been a customer with for years) saying they have activated my Volt benefits. I can see I now have the increased data limit on my O2 account. I am yet to hear anything from Virgin about the extra benefits though.

The update came from O2 because I had to manually prompt them about something (I was having trouble with the app) and thought to ask off the back of it.

We have attempted to follow the guidance with the My Virgin Media app, but I'm stuck in a loop and I am unable to find a way to activate the benefits as mentioned. 

It could be that the address format isn't matching up correctly (it doesn't allow me to format them the same way for both O2 and Virgin) but I have read there is a way for this to be manually activated on Virgin's end. 

Is there anyone here who can help me activate my Volt benefit?

Many thanks!
