Basically purchased this extension specifically for eWay payments, as at the time I purchased and up until quite recently, it was a feature listed on their website.
However after recently installing and configuring, and hours of trying to figure out what is going wrong, I submitted a support request. The answer? "Sorry we do not support it, not enough people use it."
It would have been nice to have known this before purchasing, and as such their refund policy is non-existent. I would not recommend this extension - the effort involved is not worth the $50 - use at your own risk. Have now given up and am paying a contractor to fix Joomclan's own payment plugin.
