nah.. just write up a letter with the site name and all info about what service were used and how often.. and ask for clarification on the charge back.. simple and to the point.
and if being polite doesnt work, your not gonna get a dime anyways, then its time to get even
keep a list of the guys who have charged back, and once in a while send em a letter reuqesting they settle this outstanding balance. but send it in a lude and very descriptive envelope.. so even the mailman knows whats going on. try and hid that from your wife.
It would cost almost nothing, and it would just feel so good
If everyone did this, imagine how it would impact thess chargeback BS'ers.
