If you are questioning the validity of a program you enrolled in using your Discover credit card; you have the right to request information about the program and the agreement you entered into. Credit card companies must provide their customers with information about the terms and conditions of any agreements or contracts they enter into, including any fees or charges that may be incurred. If you have requested this information from Discover and have not received it, you should contact them again and ask for the information. If you can still not obtain the information you seek, consider speaking with a consumer protection agency or an attorney for further assistance.
