It won't get blocked as lost or stolen as I have the guys address an he knows I will be there like a shot just worried over unpaid bills an blockage thank you

Contact EE and tell them you are the owner - give them his name and address if they want verification - and send them a screenshot of the advert

You need to contact EE directly and consult them and if you need to have some good security app, install Leo Privacy Guard. It hides images and videos and it also locks various applications which can be very useful to us
