Request limit reached - New Phone Number (need it for black ops6)

Hello,
I am really fed up with it, I have been waiting since yesterday, but I still can’t add my phone number, it keeps saying Request limit reached.
I have already deleted all cookies and such and waited 1 day but I keep getting the message, does anyone know how to fix this? Blizzard doesn’t seem to want to help me and always gives a ridiculous explanation.
