To the people complaining about the number of links found by software/services. Yes, I too often see this problem with link building services, and do here, but Marko was not guaranteeing number of links found, he was guaranteeing SERP movement (which I am yet to see).
The report shows most links, and you can verify the work was done, and check which ones are indexed. There were a proportion that were broken links, but most were active, and I've found a small amount were indeed indexed by Google.
But unfortunately I did not see a SERP increase. It might work better on very low competition sites not ranking in the first few pages, but in my case around Page 1 and 2 (for low competition keywords, with several sites above me with PR n/a and 0), so it looks like the refund will need to be given.
