We are sorry for the delay in resolution.
I checked the case details and found that the day you contacted our support team, Adobe's system was under maintenance. This was the reason you were asked to contact again after 24-48 hours. Also, I can see an email being sent with the same information. I assume you do not have access to your father's mailbox.
The support team sent you emails for a week and then they closed the case.
Could you reach out to them again with the case number ADB-39616618-W3Q8? Also, please request for getting your email added as a secondary email for further communication. They may ask some questions for security check while doing so.
I hope the issue gets resolved ASAP.
Shivangi,
Thank you very much for your assistance. As you suggested, I contacted the support team, and they refunded the charges to my mother's account.
Cheers,
