Edit Your Payment Type
The backend payment company, Stripe.com, had an issue with allowing subscribers to edit their payment types.
After 3 months of them working on it they have finally resolved it and added a feature to allow subscribers to modify payment types.
You can now modify your payments of Bin Db Pro by going to
https://billing.stripe.com/p/login/dR63dJbdD71Xa768ww
or clicking the "Edit your subscription Payment" button under your plan area.
