so im coming back after 12 years and im trying to make a new account as i assume my other one is long gone. the problem im having is its telling me my phone number is black listed from verification attempts and i don't understand this is the first time ive tried to enter it.. i hope this isn't in the wrong forum area i wasn't sure where to go exactly. thank you for any help you can provide.
