Refund is only available when the goal rank is not achieved at the end of the package. (Please note that the rank should be the time-period average rank, such as a one-month average or three-month average). In any case, the value corresponding to the ranking achieved during this period will always be deducted from the total received.
This service really produces great results. I tried the 10,000 for 3 month average rank package and my website stayed at that rank for almost 2 months before the ranking started to slip again. The results are almost instant. You can start to see your website move up within a week. If you really want your website to get the alexa score you desire, this is the best online service you can find. – Warren J. Gilley
