There is a building in the corner of Avenida Texas and Calle 14 in Los Jardines Metropolitanos, I dont have the number right now, but I know the place was used in the past for call center operations, the call booths were upstairs and the office and trainnig room were downstair on the ground level you can go and see it if you are in Santiago, it has a big for rent sign on its door, the location of it is a prime location on Santiago.
