Deceased estate department unreachable

I am an attorney dealing with deceased estates. Please let us have full contact details for your deceased department (e-mail and phone). It is impossible to reach someone via the normal call center as you need the deceased's specific phone number to get past the phone switchboard. Our e-mails to the normal customer service department remains unanswered. The one phone number we have of the legal department is experiencing technical difficulties. Please assist. ***
