or even a Reg E dispute based on deceptive practices by the merchant (effectively making the transaction unauthorized)?
Look carefully at 1005.11(a) and the definition of unauthorized in 1005.2(m).
(m) “Unauthorized electronic fund transfer†means an electronic fund transfer from a consumer's account
initiated by a person other than the consumer without actual authority to initiate the transfer and from which the consumer receives no benefit.
I don't care that the merchant website changed or that the website itself may have been fake. The consumer initiated the charge and they were charged the correct amount. Reg E simply does not consider this to be an error.
If, in your opinion, the consumer has not satisfied VISA/MC requirements for submitting a chargeback because you don't have enough information (e.g. what was ordered vs. what was received) then you can't proceed on the cardholder's behalf until you obtain the information you need.
