Just out of curiosity vic you claim that you're getting denied when trying to recover but how could you originally recover the account (the first time)
If you could do it once you could easily do it again?
Why can't you unlock it/recover it anymore, that makes no sense.
Before you say you dont have the IP/VPN anymore then how did you recover it when you asked Runescape for permission to recover it. Surely you didnt lose access to this 'proxy/vpn' in the space of a few days?
