Final answer:
The question does not provide enough information to specify when a travel card would be canceled for non-payment. However, it does mention a credit card company charges a $10 late payment fee and an additional $5 per day until the payment is made. For specific details on card cancellation and Salary Offset, one should check the issuer's policy.
Step-by-step explanation:
The information provided does not specify the exact number of days past the billing statement date when an account would be canceled and referred for Salary Offset by the travel card vendor. However, based on the related information given regarding late payment charges by a credit card company, we can discuss the fees applied when a payment is not made on time.
According to the provided scenario, a credit card company imposes a fee of $10 when a payment is late. From that point onwards, there is an additional charge of $5 per day for each day the payment remains unpaid. These fees accumulate daily and can add up to a significant amount over time, which underlines the importance of paying credit card bills promptly to avoid such penalties.
It should be noted that for specific details about when a travel card would be canceled for non-payment and referred for Salary Offset, one would need to review the terms and conditions set forth by the issuing travel card vendor or agency policy as these policies may vary.
