What is the ruling on receiving and withdrawing funds from Visa and Mastercard cards issued from the "Heads of Households Grant," in exchange for a commission and delivery service, then handing them over to the customer in cash in US dollars? And does the percentage-based commission fall under usury?

The questioner mentioned that credit cards are a grant for heads of households, and the granting authority does not permit the disposition mentioned by the questioner; rather, it is a circumvention of their conditions. This circumvention is not permissible. Therefore, they must either adhere to the terms of eligibility for what those cards contain, buying their necessities with them, or return them to the granting authority.
