Open Question: How do I email the Cialis company about their annoying commercial?

Hi. I don't know about other countries but, in my country of residence, Lilly (or whatever the company's name is) has created a very stupid and annoying commercial for Cialis, in which a woman sings a moronic song on a guitar, or a banjo, or something. It used to be just a stupid commercial from my point of view in the past weeks, but now they're paying TV stations to air it every damn commercial break and it annoys the hell out of me. I'm trying to email Cialis or Lilly about it, but I can't find their official email address. I tried the Cialis website and the Lilly website, to no avail. (I don't wish to waste time and money by calling them or mailing something directly.) So, could anyone give me a direct email address (or link to web form) through which I can contact the makers of this atrocious commercial? Please, I'm jumping for the remote control, to change the channel, every time I hear the cursed sounds.
