Letter from 02 today addressed to me, demanding payment for £100 for phone bill arrears. I've never had a phone from 02. Contacted them and a phone was apparently delivered to my house in August!! Someone has set up an account in my name. They knew my full address and date of birth. 02 have reported to their fraud team, and someone else will get back to me in 30 days. I have reported online to the action fraud and have a crime reference number. I have no idea how my identity has been stolen, I shred everything with personal details on. I can only assume some of my data has been leaked as I do a lot of online shopping. Can I do anything else? I'm worried I they have used my identity for other things! Thanks in advance.
