While it is an inconvience to the customer, you are setting the bank up to take additional losses if you keep the old card active. Also, if you attempt to file a fraud related chargeback on an active card, VISA/MasterCard will automatically reject your claim and the bank will lose any chargeback rights leaving you on the hook for any transactions that the customer disputes.
Once I am aware of fraud on a card, it is not negotiable to keep the card open. The customer may be willing to take a small financial hit to withdraw their claim, but what happens when the next unauthorized charge is $1,000?
As a personal promotion side note, I will be discussing other loss mitigation strategies at my upcoming webinar on August 7th.
