Carrefour Deactivated My Digital Code Without Prior Notice

I purchased a [gift code / digital product] from Carrefoursa, which was deactivated from online use without any prior notice or explanation. I received no warning via email, SMS, or on their website informing me that the code would no longer be usable. When I contacted customer service, I was told that there was a “system maintenance,” yet no timeline was given, nor was any alternative offered. This situation violates the Turkish Consumer Protection Law No. 6502, particularly the following articles: Article 6 (Defective Service): A service that is not provided as promised or causes disadvantage to the consumer is considered defective. Article 52 (Duty to Inform): Service providers must give the consumer clear, accurate, and timely information before service begins. Article 13 (Prohibition of Refusing to Sell): It is unlawful to arbitrarily deny access to a product or service that has already been sold. Beyond the financial aspect, this experience has caused emotional and psychological dissatisfaction due to the lack of transparency, poor communication, and clear disregard for the consumer. I hereby request that Carrefoursa either reactivates my code for online use or issues a full refund. If this is not resolved promptly, I will escalate the matter through CIMER (Presidency Communication Center), the Ministry of Trade, and social media platforms.
