Why is my bank account being charged twice a month?

Hello ~ Take a look here:

Subscriptions and Billing - Official Apple Support

We are fellow forum members like yourself and have no access to your account.

You are not talking to Apple support and we are not taking anything. We also do not know why and what it is for.

And we do not work for Apple. We are not machines, just volunteers.

You need to investigate this yourself.
