Hackers please read as the following information is valuable to you.  I am not NELL CALLOWAY with bill date of 15th every month now, even though she used my email address, noaccount@yahoo.com when signing up.  Spectrum cable keeps sending me spam emails with customer information.  Spectrum sable, per calls and emails, has chosen to not stop spamming me as they claim they can not help me as I am not a customer.  So please use the information to attack and gain financial benefit Spectrum Cables expense.
