Need Help with Private Relay Email Linked to Unexpected App Subscription

Hi Apple Community,

I need help regarding a subscription charge from an app (Perplexity.ai) that was made using “Sign in with Apple.”

The issue:

• I signed up for Perplexity using Sign in with Apple.
• The account is tied to this private relay email: d***********@privaterelay.appleid.com.
• I was recently charged for a Perplexity Pro subscription, but I did not authorize or manually initiate this transaction.
• I tried contacting Perplexity support, but they’re asking me to write from the email I used to sign up — which is the private relay email that I can't access.
• I’m the legitimate owner of the Apple ID linked to that private relay address.

Is there a way for Apple to:

• Help me verify ownership of the relay email/account,
• Or contact the app developer on my behalf,
• Or provide any documentation I can send them to prove the account is mine?
• Also, is it possible to request a refund if this was billed through my Apple ID?

Any help or guidance would be deeply appreciated!

Thanks in advance,

Swenn
