Since the virgin to o2 changeover, when anyone calls who is in my contacts, it comes up as unknown number ?

This is a customer to customer community, not O2.
You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202

Sarah's suggestion worked, turning off the 4g calling option in mobile Network settings Thanks
