I sent them feedback on it, for whatever that is worth.
After using Googles Adwords, where I can make simple changes like bid prices in a few seconds, spending 20 minutes just to find the right page (and then having to wait for it to be approved) seems a bit off.
I can only imagine the support staff are all too aware that they have a very poor product. Obviously they can't come out and say this in public and thus we have to trust that there are better things in the pipeline.
How did they get it so wrong - all they had to do was copy Adwords.
