You did the right thing by contacting Bandai, give them your user name, rank, all the characters you can remember, the last team you used, since your brother have you in his friendlist ask him what your ID is and give it to Bandai too, it seems that you have a purhcase history within the game, so give Bandai too, giving them all this information will speed up the process.

Just remember is a slow process, it might take a couple of weeks but you will get your account back, for future references, make a transfer code and keep your account link to facebook.
