If you would like to refund you will need to go through the refund section on OSBot, I have no control over the matter.
That being said, 99% of issues here are as a result of invalid setup, if you could send me your configuration I may be able to help more.
Tips:
Make sure your 'safespot tile' is set, I believe the hotkey to do this is F3, but you should see it up the topleft. This is essentially the AFK position. You also want to enable safespotting in the settings if its an option
