I managed to get a PAC by clicking on the link when I signed into my account. It displayed it straight away (along with its expiry date ) and I also received a text confirming it.
The bad news is that there will be no refund of any unused credit - which in my case is £12, Maybe a small amount but if every payg customer has that same amount when the plug is pulled on the service - 130,000 x £10 adds up to a sizeable windfall for Virgin. I am gpoing to make sure I use a lot of it before the service is withdrawn
Thank you for expanding on this. Have you ordered a new SIM card recently at all? I can see in one of the text messages in your screenshot that it's suggesting this may be the reason that this is happening.
