Surely. If a surfer has had a membership before through a widely used biller they'd have experience walking through the cancellation process. But without you listing the actual billers used the only thing to do is speculate.
Unless it from what the carding programs do, set up a "fake" cancellation domains, make the member think his membership is canceled when its not and just keep on charging the card until the member has to cancel it. Oh and charge him for new memberships on top of that.
