Escalation department email or direct contact line

I was supplied ne865k: I fully understand that you would like to be removed on the AT&T Risk Spam list so that your customer will be more comfortable getting in touch with you. Removing your phone lines from this list is usually being done by our Escalation Specialist over the phone as this process is highly confidential for the security of all the accounts we have. We can absolutely partner with them today. I can help you with providing their complete contact details for you quickly. Would you like me to share it now with you?
Me: yes please

ne865k: Please partner with Customer Care Department 800-331-0500 and they are open from Mon to Sun 8:00 AM to 12:00 AM ET. I assure you that removing all your lines from AT&T Risk Spam will be taken care of once you called this number.

However, I have been on the phone with 3 different people now for a hour and have not had the issue addressed and now on call waiting again. We need our Business Phone line removed from your AT & T Risk Spam so our customers will answer our phone calls as we are not Risk nor Spam
