Problem with my Authenticator due to change of Country

I need help to use my account again . When you activate the authenticator I lived in the United States so I had a number from this country, but I returned to my native country and here I have another number, here in my country I closed the battle net session and when I tried to open it again it asked me for the code that sends the number with it which the Authenticator was created, so since I now have another number it won’t let me log into my account. By the way, this is another account from which I am speaking, I cannot access my main account, and it is the one I want to recover, please if someone can help me recover my main account I will be very grateful. First of all, Thanks.
