I have reached the employee´s boss down in Mexico City and still no answer!! I suggest you do the same:

pespinosa@sre.gob.mx

that happens to be the Minister of Foreign Affairs!!! (Ms.Patricia Espinosa)

Now this emploeyee is in Canada, where Visas to Mexicans were restricted!! Any coincidence? What kind of Diplomats does Mexico have??

Do the same and demand an explanation or public apology!!!!! I think everyone in America DESERVES it!!!
