I have been locked out of my account

Someone has hacked into my account from a unfamiliar location and changed all my personal information pertaining to my ea account. I would like to get back in I have tried contacting customer support and they have not helped me one bit!!! EAs customer service is terrible and there security is pooh! If you can resolve this issue in a timely manner i wll remove my comment and be satisfied with the result but until then EA can kick rocks! you will not get a dime frome me no more, same goes to epicgames, steam, and microsoft. Im tired of the constant security breaches. This doesnt go unnoticed lazy people do lazy work.
