As promised, following up. Auto-reply from Costco said 24 hours. Still nada at 40.... reminder sent. 800 number NEVER not busy. Did what was left to me.
1. Tried to talk on phone to Televisa (Guad AND Mexico city). Newsrooms were always too busy to answer.
2. Have now sent emails to Televisa and heraldobinario, and left voice message at Milenio news room line (ref: the links) ... asking in all cases they follow up their stories with ALL big companies, but these 2 in particular, because they're taking advantage and are in non-compliance with Federal law that was in no way a surprise. Emphasized this hurts Mexicans trying to feed themselves, never mind their pets, these days.
Results IF they happen. Meanwhile always remember.... it is NEVER good to piss off old people with too much time on their hands! 😾😾😾
