Hey Weborithm, sorry for the confusion. An email should have gone on out to any seller that had an issue. Anyway, this week we integrated a new cart system on MOJO where we now accept all major credit cards on our site rather than just PayPal. We are using Authorize.net as part of our system and this first week we have seen some fraud charges come through. Weve worked with them all week and added more layers of Fraud Detection and from what I can tell I think we've got it all sorted out already. With that being said, there was a handful earlier this week that you most likely saw get charged back but like I said, with the new setup, I think we are set.
If you have any other questions please feel free to ask or email me any time.
