My phone number changed two years ago.
I tried to change it, but it was in vain, because they send a confirmation text to the old number. Which is no longer live.
I asked support for help two years ago.
They wrote: The Overwatch 2 team has made the decision to remove phone number requirements for a majority of existing Overwatch players. Any Overwatch player with a connected Battle.net account, which includes all players who have played since June 9, 2021, will not have to provide a phone number to play.
So they didn’t help me change the phone number.
I have now been asked to confirm my account with a phone number. Since they are texting me to the old number, of course I can’t confirm it. So they locked my account.
So I have been penalised for their mistake.
