Paul, can you quote the law regarding this? User Iduna did research on this topic and concluded it is not against costa rica law in the thread titled "best way to ship computer" she said this
I decided to take examine the whole "it is illegal to say/write anything negative about a business, person, etc. thing" that I have heard so many times. On the surface it appears that this cannot be correct since many people make public complaints about businesses, government agencies, individual professionals, etc. in many different forums, including the Letters section of La Nación. I looked up the section on "Delitos contra el honor" in the código penal. This is readily available online. It seems pretty clear that it is perfectly permissible to publicly complain about an experience with a business or a person in a professional capacity as long as you do not directly impune the business's or person's character, honesty, accuse them of a crime, etc. So, in other words, it is perfectly fine to write or say something like, "Sky TV charges way to much money for a crappy picture and they never respond to complaints". Or "Restaurant Such an Such serves steak that is as tough as a shoe and the service is slow." Or "Doctor Jones was very rude when I went in for my exam and charged me more than he said he would." It is NOT OK to say or write something like "Cielo TV is run by a bunch of crooks that are stealing money from all of their customers". Or "Restaurant Such and Such serves expired meat that can kill you". Or "Doctor Jones is pervert and didn't even finish medical school".
Here is a quote from one section of the law that addresses this:
Exclusión de delito
ARTÍCULO 151.- No son punibles como ofensas al honor los juicios
desfavorables de la crítica literaria, artística, histórica, científica o profesional; el
concepto desfavorable expresado en cumplimiento de un deber o ejerciendo un
derecho siempre que el modo de preceder (sic) o la falta de reserva cuando debió
haberla, no demuestren un propósito ofensivo.
