Did you contact him with the correct channels??
For refunds - I am dealing with Mindaugas for almost two years and everything was solved with him if you use his DIRECT SUPPORT DESK AT
http://www.adsenseboy.com/support/index.php
or email him at
THE REAL PROBLEM IS ACTUALLY PLIMUS!!!
He is using plimus for his payment processor and plimus has cheated many
affiliate sales out of me and the communication between plimus customer
service and their customers is a NIGHTMARE. So I had major issues with plimus
but NEVER with Mindaugas as I have close contact with him.
And his scripts are checked for validity and if someone forces a refund the software
stops working of course. If you have install problems or anything you submit a support ticket and usually get a reply within 2 working days!
And I can tell that his scripts are working, I use them for almost 2 years as well.
