Diablo immortal

hi Blizzard, I have tried several times to log in with my profile in the game Diablo Immortal with my character who was at lv 224 my account my battle tag “mirolast # 2257” and I am registered in Battle.net, I also bought the passage! I don’t know if there is a problem with the service or directly in the game, but I cannot log in with my “Mirolast # 2257” profile even though I am also registered in the cloud to avoid this type of problem! I ask as soon as possible your assistance and also your answer for clarifications !! On recording, he gives me the battle tag Mirolast # 2900 until the 19th of September, I played with the name Mirolast # 2257. For an audio problem I uninstalled the game, but He no longer gave me my battle tag only for may i know how to get my mirolast # 2257 back to resume my playable character. I await your reply thanks
