Xbox Game Pass Refund Confirmed but Money Not Received

I purchased an Xbox Game Pass subscription for PC through Microsoft and paid $9 by bank card. After using the subscription for a few days, I canceled it on the 16th. Microsoft sent me an email stating that I would receive a refund for the unused days of the subscription. However, despite receiving this confirmation email, no refund has been credited to my bank account.

A reasonable amount of time has passed since the payment and, in particular, since the cancellation, yet the refund amount has still not been credited to my account. I tried to contact Microsoft customer service, but I was unable to reach anyone who could assist me, so I have also been unable to find out the current status of my refund.

I request that the $7 refund for the unused days, which Microsoft promised and confirmed by email, be credited to my bank card account as soon as possible.
