Having been in this EXACT position at Ezeiza for my own cancer meds, I totally understand. We spent 4x what they cost on taxes and door to door shipping and I never got them, nor were they returned to sender. It set me back and made my life a hell for quite some time, and unfortunately I haven't been able to leave the country for six years now so it is an especially powerless feeling.
Again, I am so sorry for the original post here, which was made in good faith. I really hope that you are able to resolve this - I had no idea that the company was so devious when I recommended it. I had really scoured their site to see if it was what they presented it as and thought I'd struck gold. I will keep an eye on this post and I wish you the best.
