Subscription issues in the Google play store

[Rimo梨木]

I correctly subscribed the advanced content in Google play the day before, but the subscription expired the next day. I confirm that the steps I subscribed were carried out according to the official website, and I did not make any mistake. Besides, I found that many people have this problem for many years before, I would like to ask how to purchase and use it normally in Google play. which is very important to me.Below is my purchase voucher and an in-app screenshot

I don't understand why I can have such a serious problem with paying for software, the experience is not even as good as directly using pirated software, how can we support you, why you can not fix even one purchase problem for years.
