Currently traveling for summer abroad, bought a 50 dollar gift code for itunes on my phone, turns out the code was fake so tried looking for the make a claim button on the g2a app, can't find it, decided to go on the computer to try and find the claim button, turns out I need to have access to my US phone number to log in. Tried contacting support, apparently wait time is 72 hours. 2 factor authentication needs a button where you could still gain access into your account when you don't have access to the number registered due to travels and such.
