so... i finally got my ticket!!
i called to seetickets, they told me that my ticket is in Romania, i called and went to the post office and discovered that seetickets printed my address with errors: not my full name and the apartment number was incomplete, and that's why is hasn't got to me.
now i'm super happy and i can't wait for Wednesday morning when i fly out to london and then... glastonbury here i come!
thank you all for your help!
