By the way, one thing I wanted to add.
You dont have to be mad on the billing companies always behaving like Credit Card processing is some secret science magic which can not be explained to mere mortals , the Gandalf way of talking.
The problem is that in the Acquiring banks themselves quite often employees can not figure out what the fuck this rule means and what the fuck that and which one applies and which one doesnt.
We couple of times called to Visa London to the department which issued IPSP rules. Beleive it or not , since the person who signed those rules was unavailable, they coulnt find a single living soul to explain ANYTHING.

Although I spoke to several risk management department managers, to VISA CEMEA and EU reps and this kind of people. And You have to understand - that headquarters for fucks sake!
So what do You want?
Ibill CEO or Epoch CEO coming out here saying: "Hey guys! I got no FUCKING idea what they mean by "principal" , where the fuck Cyprus and Gibraltar are located according to them, what the fuck is 3D Secure and how the fucking hell we now calculate chargebacks according to the latest rules and regulations. Excuse me for not knowing this shit. By the fucking way, guys where should I keep Your 80 million? My top pick is BNP ParisBas guys, but Serge called and said their fees are crap so now what ?"
Remember how Epoch and Ibill did press releases how they gonna run transactions on Verify by Visa and never did? Well...take a hint...
But it's impossible to blame them for it, cause they are not the people who are supposed get the rules and explain them from card associations.
