Reason code 76 chargeback: always ask for full chargeback in the first instance. Never offer to calculate what the amount should have been as it is merchant's obligation to post in local currency properly after chargeback completed. Only where issuer does not offer to chargeback do you accept a calculated settlement.
I don't think that is a proper use of chargeback. You are only supposed to dispute the cost of goods or services you did not receive as agreed upon. For example, if you book a round trip ticket and the airline goes bankrupt after you use the first segment, you would only chargeback the portion you couldn't use. Since you did receive the goods you wanted to buy but you did not request the service of currency conversion, you should only chargeback the latter.
