Call SWTOR support using the appropriate number from this list: https://help.ea.com/en-us/help/star-wars/star-wars-the-old-republic/swtor-support/

Of course you'll have to provide identification, so knowing the answers to your security questions would be optimal, if you don't know them out of your head, maybe you'll guess/remember when they ask you the questions.

I'm very grateful for your help, but the thing is that i'm from Brazil and there's no number for here. I'd like to know if aren't there any other ways to get in contact with the service. By the way thanks already.

You can call them via internet call:

Using VoIP to contact support

You may also use Voice Over Internet Protocol (VoIP) services like Skype, Viber, or Google Voice, to call Customer Service, regardless of where you are calling from.

International calls made using VoIP are generally far less expensive than calls made from a mobile phone or landline.

Open the VOIP program or app of your choice, then:

If you’re calling for support in English:

1. Set your country to the UK.
2. Dial 0203 014 1826.

Since Brazil's time zone is close to the US' time zones you should be fine if you call in the (early) afternoon.

Thanks for the support buddy I appreciate. Just for the record does it cost anything this VoIP call?
