La palabra advocate puede ser usada en varias formas pero en esta instancia es utilizada en la forma de un asesor o consejero

Si seguimos la lógica de la respuesta de mi colega, creo que "encargado" es una opción válida también: "Encargado de servicio al cliente"

Suerte!

Creo que todas las demás opciones te las han dado lo anteriores colegas.

Suerte y saludos

Yo lo diria asi.

Si cupiera, por las funciones q realiza, tal vez pondría Supervisor, porq el sentido creo q es: quien fiscaliza, vela por, controla, cosas así.

Coordinador Regional del Area de Servicios al Cliente.

I really am hesitant to agree with those who say "advocate" should be translated as "encargado" or "supervisor," because an advocate does not necessarily have to be a person in charge. Really, I think the meaning of "advocate" should be clarified with your client. For example, there are many different position levels at my company that have standard names, yet refer to many different kinds of positions. There are representatives, senior representatives, coordinators, senior coordinators, administrators, project managers, etc. In our case, the titles "representative, coordinator, and administrator" rarely encompass the true nature of the person's job. Sr. coordinators and administrators are generally in some sort of supervisory position, but that is not always the case.

In your case, "advocate" could mean many things. Encarta says this: Adcovate 1. somebody giving support: somebody who supports or speaks in favor of something a tireless advocate of social reform.

If you look at it this way (which I am inclined to do), it seems that advocate is just a fancy name for "representative." It may be a promotion up from "representative," possibly making this employee a point-person for the department simply for their know-how. In that case, I think that "asesor" would be a great selection (refer to my "agree" above!) However, if your client agrees, "coordinador" might also be a good translation.

Anywho... I know my answer is wordy, but I hope it's helped some. Good luck!!!

Laura,
Aunque tarde, tal vez te sirva saber que en México se le llama síndico del consumidor
