as said contact a gm about it, or report yourself "cheating" in explaining the sitution.
We have some system to catch multi account during signups, they sadly don't work everytime but sometimes we also get a brother/sister and believe it is an second account. In this cases i normally say, make a note in the "reasons for country change" section "like my brother also play BB" and after the signup, text a gm that he could note the connection betwen the two accounts.
And attention, don't make transfer betwen them.
