Hi J'sdude,
From our testing, our customers get retrieval requests in around 50% of cases. So we get a chance to help them answer them before they become chargebacks.
The big thing tho, this actually deterrs chargebacks from happening in the first place, so your incidences of these chargebacks coming through are greatly reduced anyway. It pretty much eliminates outright fraud (what password hacker is going to want to use a stolen credit card when he has to ring up on mum and dad's phone line) and severely reduces friendly fraud.
When a chargeback does come in however we have had enormous success in ringing people as soon as we do get the notification. People *ARE* able to reverse a chargeback, but the surfer has to ring his bank and ask them to reverse it. Also, once you get the first one, you're able to contact them immediately and stop them from charging back other ones that they might be about to hit their credit card statements.
In fact, most chargebacks we investigated were because the customer didnt recognise the descriptor on their statements. When we told them what it was for, they were fine about it. At least with this solution you have a concrete way to contact them to resolve any issues.
The bottom line is that in all our testing it has worked marvellously to drop chargebacks and fraud significantly. We're hooking up a heap of Pennywize clients now, so in the next few weeks you'll have alot more people to come forward and give their own analysis
