Google One Subscription Price Increased by 400% Without Warning

I subscribed to Google One under the plan that charged ₺2.99 for the first two months and then ₺9.99 per month afterward. However, just four months into my membership, I was informed that starting from the fifth month, my subscription fee would increase to ₺49.99—a shocking 400% price hike!

How is this kind of drastic price increase justified? Such an extreme change is completely unacceptable. No reasonable business practice allows for such an absurd price jump in such a short period. I feel tricked and taken advantage of. Google must explain this unreasonable price surge and offer a fair and transparent pricing policy. I demand a review of this excessive price increase!
