Hi all,

I have released a Delphi program and I wanted to advertise
on Google, using their AdWords system. For those who don't
know, it is about your ad showing in the right part of
web pages when you perform a search.
To my very big surprise some nasty things happened.
First, their system doesn't work well, my ad does not appear
in searches the way I set it up.
I tried to contact their support. I found that they have a
very slow support, which even doesn't work weekends (!!).
If you email them on Friday they reply the next Tuesday.
Anyway, in the end, all they did was to send me quotes from
their help files but totally failed to answer any particular
question. Finally they completely stopped replying.

What should I do?
What alternatives are to promote my product?
