Player gone after Gamertag change :(

Decided to change my gamertag to something cooler, which made ea skate log out of the game when signing back in I was forced to make a new character and back to tutorial island. I paid for the founders pack, The DIY spaceman suit, and grinded all the way through the season 1 pass for it to be gone forever. Would love to have my account back please help an og digital skater out. Look into it as well i would hate for this to happen to another fellow skater.
