When an advertiser (in this case also a blog) targeting specific sites through Google's CPM program ran into problems with its advertising campaign (its ads - or parts of them - were showing up sometimes up to four times on the same web page), Google customer service reps apparently couldn't fathom (via ReveNews) that they were dealing with the advertiser, not the publisher, and that the issue had to do with CPM, not PPC - and then kept offering "a credit of $90 towards your Google AdWords account" when some 90 percent of the $1,000 allocated to the site had already been burned up for ads displayed incorrectly or multiple times.

"They need to hire someone from the CPM banner market to manage this program and retrain the staff, otherwise I will be one of many unhappy customers," wrote Pace of in the 92.5M blog.

"It's obvious that google is growing so fast, with so many customers that they don't have a clue how to really service them…. They are offering a new system of CPM, and since all their staff has been trained on PPC, they have no idea how normal CPM ad serving should be done, what are standard practices and even why I deserve a full refund."
