Details: I am trying to renew my PC subscription on the Mogstation. After entering my credit card details, the webpage gets stuck in a redirecting loop. I have tried with a different credit card and with ad blockers disabled in Google Chrome but it keeps going through the same thing. When I switched over to Microsoft Edge, I got past the redirecting but the moogle returned an error: "An error has occurred. Please confirm the status of any relevant options and then try again. For details, please contact the Square Enix Support Centre. (Error code: 601)". The £1 test transaction is now showing up on my credit card account despite not getting as far as adding my subscription.

I renew my subscription this way every month to manage my spending but this is the first time I'm having this issue
