Got a £0 ChatGPT Plus trial invoice marked Paid, but my account still says Free. Could I still be charged?

A user on October 25 signed up for a one-month ChatGPT Plus trial, receiving an official invoice for £0.00 marked as Paid after entering card details. Despite the paid invoice, their account still displays a "Free" status. The user is seeking to determine if a subscription was actually set up and if they could still be charged, as they are unable to get an answer regarding the subscription status.

This report highlights a unique billing discrepancy where a user received a paid £0 invoice for a ChatGPT Plus trial, yet their account remained free, unlike typical trial activations.
