I received a letter saying my SIM won't work from Friday, and to insert the new one. I haven't been issued with a new one. I'm unable to contact Virgin (call centres closed, "Message Us" open for 90 minutes or so without a response).
yes it took 3 hours for the text message thing in the website to get back to me. They checked the SIM card number and it didn't need anything doing as it was a new enough version. Which begs the question, why did I get a message? If they can check the numbers, why not just contact those who are affected rather than just everyone and lead to a huge waste of time. Terrible! Hope you got yourself sorted too, and thanks for the solidarity!
