One of our few charge backs for hosting we received, that we won too at that.. Has a pretty high post count in this community. I won't go into more detail then that until a mod gives the green light on name and shame as they aren't worth getting in trouble for here.
I'm sure your aware of how when those types of threads have been posted before, they boil down to he-said she-said arguements as posting PM's or emails is against the rules.
If a member has done chargebacks, drop us a ticket and we can note it down on their account, prolific users have been and will be removed.
