I apologize for the troubles that you've been facing with the subscriptions on your account.
I did check your account details and see that the 350 images plan is active under your personal account.
I believe the issue here is that you might be viewing your teams account on the Stock page which has a different Stock subscription plan.
Kindly switch to your personal account from the top right of the Stock homepage and select the correct account.
Let me know if you still face the issue.
