Customer lost wallet/card and sees unauthorized transactions on his account and timely notifies bank. Unauthorized transactions total $2,239.18, Bank issued provisional credit, but also needed to include interest and failed to do so. How is the "interest" reimbursement calculated in a dispute situation like this? The interest rate on the account is .05%. There were only two days from the date the unauthorized transactions posted to the date provisional credit was credited to customer's account. Can someone provide a calculation for this?
