chargebacks suck the fat one!
they are abused and too easily given! All you gotta do is call your bank and tell them ?fraudulent charge? and boom you instantly win. It is bullshit. Sometimes chargebacks are necessary but not every charge on your statement is ?fraud?.
it all comes down to if the cardholders bank wants to give them the chargeback or not.
you can have a signed agreement and the dude has a $50k line with a bank - he will still win because the bank does not want to lose them as a customer.
I lost a merchant account once due to chargebacks. Learned allot from it.
good job on the bust!
