Why won't my Starcraft 2 login work?

It's highly likely that your account was compromised so you need to get Blizzard to give it back to you. Hopefully you created your account with your real name as that is going to make this a lot easier. You will need to be able to prove you are who you say you are, they usually ask you to send a scanned copy of id (passport or something) to them. As long as you can prove it is your account, they WILL help you get it back, they have one of the best customer services around. Go here again (I know you tried recovery already) https://eu.battle.net/account/support/account-reco... At the bottom of the page click begin account recovery then on the next page scroll right to the bottom and in small type you have the option to click to open a ticket. Choose the' I can't login option' and then 'I have another issue not listed here' then hit Submit ticket. Choose to submit without logging in (since you cannot) then fill in as much info as you can and explain the issue to them. If you can't remember your secret question it's even more important you provide the ID. They will ask you for a phone number because they have a new feature now called call back where once they read your ticket they can actually call you to help you fix it now instead of you having to call them and wait on hold for ages. I believe this is the number they are asking you for since none of the security questions are for numbers. You just need to give them a phone number they can call you on. I hope this helps you and you get your account back, good luck! Alos don;t forget to scan your computer for viruses and trojans since they got your info somewhere and the last thing you want is to get your account back and lose it again tomorrow.
