Account Hacked

Hi, My name is Spookboy, i am posting on my sons account because my account was hacked on the 15th August 2010 around 1700 hours.. As soon as the hack was noticed, within minutes by my son who was online, and put in a ticket, The GM replied almost instantly, and said the account is locked to prevent damages and losses. My son tracked down my toon, and watched all my banks alts withdraw all my items from AH, and open up trade with a lvl 1 character. Took abt 4 tickets from my son, and numerous guild members to put in tickets before the account was actually locked, thus everything was gone by then.

Now here is the strange part, My battlenet login account is with a ISP service that i no longer use, hence my emails cannot be accessed or retrieved etc. How could the hacker get in and change all my details? Without the confirmation emails. I rang up my old ISP to see if i could have the emails forward to my sons email address, but was told, not even they can acess the emails. So again how could the hacker get the confirmation emails?

Now my problem lies in the fact that i cant do much cus i cant log into battlenet to do anything or change my battelnet account to my new email address. Phone support is virtually impossible to get a hold of, my work hours dont allow me to call during the PST. its 2am in the morning for me,

Would a technical support officer be able to contact me via my sons email address attached to this (forsakon) account. so we can organise a new email address for my battlenet account and password and to apply the authentorcator that i purchased and recieved, only 2 days ago.

Thanking you's for your time,

Spookboy
