Problems with resetting passwords

My account has recently been hacked and has sent an email to my dad and some other random companies like SKY and Origin, in which was a link to an explicit adult site so yeahhh. The other thing is the referral account which I would like to send the reset link to has also been hacked and I think the password may have been changed on it. It also seems that the referral for that account is set up so if I have to reset my password, it will send it to itself. Pointless I Know. The security question for this one is also unknown, I've tried a few. Now you would say the only way to reset the password now is to fill out the questionairre thing where I put as much info as I can in it and hope for the best. I've tried and failed. I don't know what to do as there are some things I need to access and frankly I'm scared that someone I don't know can access it too, they know all my personal details and that freaks me out. I've also tried ringing up customer services and all that does is to tell me to go to a website! Which ISN'T what I want. Help, pleaseee, surely there is another way to access it.
