Blizzard Region Change

I created my account years ago, Im not sure what the reason is but my accounts region is set to GB.

Trying to log in to overwatch 2, Ive been informed that I must use my phone number in order to play the game,I live in Israel and to change my region I must provide an utility bill.

duo to not being written in english ( but in Hebrew) Customer Support wont accept my bill, what can I do to actually change my game region to the one Im actually playing from?

Please , any kind of help would be appreciated!
