I apologize for this experience.
I did check your account and see that you were promised the refund under case# ADB-1104124-G8L6 but it still hasn't been credited to your account.
I am getting this case checked and will be updating you for the same.
Apologize for the delay.
The issue has been taken care off and the refund has been processed.
Feel free to update this thread in case of any additional questions.
You are welcome!
