How to renew ChatGPT subscription at the previous price after forgetting?

I had subscribed ChatGPT about 2mounth ago, 2 days ago, I redeemed enough amount to pay a new subscription, but I forgot to press "renew" button. Until now the price is changed to ₺999.99, instead of ₺499.99 yesterday. I hope there is another way to help me use old price to subscribe again.

Thanks.

Here is some imgs to show its only expired for old price only few hours
