I called whastapp and a woman, an employee, would forward my number to another employee responsible for the rentals. 3 days after nobody called or called me, I decided not to call whastapp anymore, but to call. They answered me and the same thing, they said they were going to call me immediately, because I was already waiting days. Well, in short, it's been 1 week and they didn't call me and I couldn't be seen. I already rented the apartment to another real estate company today.
