WotLK Problem with old account

Hi guys,

I have some troubles with my old account.
So, I was playing this couple of years ago, since then, a lot of thing happened in my life, I moved to another country, came back and decided to try with wotlk again.. but.. I am not using my old email, because I forgot password and I created a new one when I moved abroad and I dont have my old phone number anymore. Here is the problem. Of course, I also forgot the password of my in-game account..
Please, I would appreciate if u guys could help me somehow with that, I believe that account and characters there were "nothing special" but for me, its important, nostalgic, kinda special..
Only thing that I know is that my in-game username was "alexban" and I am not sure, but I believe nickname of one of characters were "Lytara" - Alliance Shaman.
There was also one Hunter I believe..
I would really appreciate your help and please let me know if something more is needed, maybe I could remember something as well..

Thanks in advance.
