What is the ruling on working in customer service for a company that sells discounted airline tickets, and requires an initial free subscription to be followed by the collection of a specific amount later from the credit card without sufficient clarity to the customer, and obliges the employee to prevent customers from canceling the subscription?

Writing a condition in small print does not invalidate the contract, nor is it considered deception, because the contracting party is required to read all the conditions. The problematic issue lies in the company's method of operation, which involves paying an annual subscription to obtain discounts (paid discount cards). This is prohibited by many contemporary scholars, and a resolution to that effect was issued by the Islamic Fiqh Academy due to the element of gharar (definition) (uncertainty); the buyer pays money without knowing what they will receive. Thus, a definite loss is incurred in exchange for a potential gain, and the Prophet (peace and blessings be upon him) forbade gharar sales.
