Recurring $90 charges and difficulty contacting Apple support for refund

This sounds like either your Apple Account (formerly Apple ID) or your payment method is compromised. Contact your bank to dispute the payments.

If you think your Apple Account has been compromised - Apple Support

Here's how to request an app or media refund from Apple (From: Request a refund for apps or content that you bought from Apple - Apple Support - see the article for more detail.) If you bought this in the EU from a third party, see: About purchases not billed through the App Store or the App Store’s In-App Purchase system - Apple Support instead.

1. Sign in to https://reportaproblem.apple.com

2. Tap or click "I'd like to," then choose "Request a refund."

3. Choose the reason why you want a refund, then choose Next.

4. Choose the app, subscription, or other item, then choose Submit.

If you were charged for a subscription that you no longer want, you can also cancel the subscription using the directions in this article --> If you want to cancel a subscription from Apple - Apple Support

Read this support article for information about how long it takes to receive a refund (if you are granted one), and how to check the status of a refund for apps or content that you bought from Apple --> Check the status of a refund for apps or content that you bought from Apple - Apple Support

If you do not see the purchases on your account, do not share a credit or debit card with another person, and are not a Family Sharing Organizer, you may be a victim of card fraud. Contact your bank about that. It is not Apple's responsibility.
