Türk Telekom's YouTube Premium Free Trial Scam

When you sign up for a new plan with Türk Telekom, they offer a complimentary 3-month YouTube Premium membership. Nevertheless, in cases where the link they provide fails to function, they adamantly deny any accountability. I'm having trouble grasping this deceit. According to the rules, registration should be completed within a month. I attempted it, but unfortunately, it was unsuccessful. Now they're insisting that I should have informed them within 1 month. It feels like I was the one who made the promise, not them. You are expected to inform them within the timeframes they have set, as they have not kept their own promise. That's hard to believe.
