There is 11 missions we have to complete, however its not fair that one of them is "keep your old number"
I can't do this last mission because giffgaff was my very first number I ever got! And Im proud of that but at the same time im not on 100% because of this mission.
Im sure there is more people like me and cant do this mission.
There should be an option on this mission like: "Giffgaff was my 1st number I dont have an old number to keep"
