I have been futilly corresponding with Yahoo for over a week. It seems that somehow they blocked our business e-mail account. After many,many tries and e-mails they said my birthdate did not match! I have said they could check my other accounts for birthdates to confirm-no response. This is not a new account-we have changed the password already witout problems. I also am unable to complete successfully any of the security numbers/letters. According to them. I have explained that this address is on multiple websites, business cards, and our e-mail account with our office- which we have not been able to view. They just ignore me. I have tried and tried to get a telephone number, to no avail. Can anyone help, please?
