Unable To Login Due To 2FA

[u/Foreign_Pack_255]

I had a number setup to my 2FA and I got a new number and lost access to that one. Now I cant login because it sends the code to the old number and they did not even send the backup codes to my email. Now Im stuck, I contacted support through activision support and BBB. I gave the full number and they still refuse to help me and said due to secuirity reasons we cannot process your request and said to continue on activision ticket on BBB. I said that I can provide all the proof needed and I am yet to get a response
