Charged for Meta Horizon+ on a deleted account, and I have no way to contact support

Hello,

I’m being charged for a Meta Horizon+ subscription, and I can’t find any way to contact support about it.

The subscription comes from an account I used at a previous VR company. I’ve since left that company, so I no longer have the headset, and the account has been deleted. I can’t log in to cancel the subscription, and I’m being charged ₩10,438 (“Occlus”) on my card.

I tried to contact support, but the portal asks for a device serial number or an order number. I have neither the device nor access to the account, so I can’t open a ticket.

I need a way to reach Meta Support (or a Community Manager) to cancel this subscription and request a refund. Could someone point me to a contact method that doesn’t require a device, or help escalate this?

Thank you.
