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.
I have many websites, and every time I launch a new one I turn to Rankstore.com to help with the traffic. Never ceases to amaze me. Great job!
