Blynk pro plan has been double-payment

I changed from the maker plan to the pro plan on November 1, but when I checked on November 5, it was changed to the maker plan again. So I repaid it to change it to the pro plan again, but will the double-processed amount be carried over to next month?

P.S. On November 1, we confirmed that it was a normal pro plan.
The payment on November 1st was made to Google Play Store, and the payment on November 5th was made on the blynk site.

Hi,

We need the email of the owner of your account to check this on our side.

Also, please check what PLay store shows for you in case of Blynk IoT app subscriptions: which one is shown there and how it works. Play Store → Avatar click → Payments and subscriptions → Subscriptions → Is there a Blynk IoT sub inactive?
