system limitations and refund payment

I would like to report an issue regarding my recent subscription renewal and user plan change.

Since 27/2/26, I notice that my plan needed renewal. However, the credit card registered on the account had already expired, so I needed to update the payment method. At the same time, my company planned to reduce the number of users from 2 to 1.

Since 2/3/2026, I tried several times to downgrade the number of users before renewing the plan, but the system would not allow me to click or make any changes. I also checked the steps provided by ChatGPT support, but the options they mentioned were not available in my account interface.

Because my subscription had already expired last month and I had an upcoming meeting that required more than one hour of usage, I had no choice but to proceed with the payment first. I updated my credit card details and the system immediately charged my bank card. However, there was no payment confirmation pop-up and I did not receive any OTP verification from my bank when the new card was added or charged.

After the payment was completed, I went back to the user plan management section and suddenly the system allowed me to downgrade the number of users from 2 to 1. I immediately contacted the live customer service agent and requested a refund since the renewal payment and the downgrade were done within less than 5 minutes.

What surprised me further was that the invoice stated the payment date as 4/3/2026, even though the transaction actually happened on 5/3/2026 around 9:15 AM. I was so confused that I even checked my phone to confirm the current date.

To summarize my concerns:

1. I attempted for several days to downgrade the user count before renewing, but the system did not allow the change.

2. The payment was processed immediately after adding a new card, without a confirmation step or OTP verification.

3. The invoice shows an incorrect transaction date.

4. The downgrade request and refund request were made almost immediately after the renewal (within minutes).

Because the downgrade was done almost immediately after the renewal, I believe a refund or adjustment would be reasonable. I have already provided my email to the live support agent and am currently waiting for their response. 
This situation occurred due to system limitations rather than user intention, and I hope the billing team can review this case and provide a fair resolution.
