What can we do if we cannot or have problems obtaining a name of the wo/man we want to send our notices to? for example, I have the name of a general customer service agent, of a corporation, who is my point of contact regarding a complaint. However, those wo/man who are actually making the decisions that cause harm to me I’m having difficulty obtaining their names. Would I then just send the notices to the wo/man general customer service agent who’s name I do have?
