I mean I want to know where they got all this information jagex says they have on me?
Not from me directly via my email as that has been secure, I haven't mentally let jagex off the hook yet for having lost my data internally...
We didn't lose any info. The appeal came in with all the info we have mentioned, and was identified as the owner based on that info. I am unable to see how the info was compromised - there are many suggestions on this thread. Best advice is the that given on the Support Centre.
