Can't be done here as we are all customers.
You may be able to change it in MyO2 or phone sales
Looks like you should contact the sales team they can help with that – message them on Social Media if yo can - on Facebook (https://o2uk.co/O2CFB) ,
Twitter (https://o2uk.co/O2CTW) or
Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255, free from any phone
This is not O2 and we are all customers here similar to yourself and cannot answer account type queries.
