How long does an Azure refund request take, and what are the chances of approval for unexpected charges incurred during personal learning?

Hello Microsoft Azure Support Team,

I am an individual learner using Microsoft Azure solely for educational purposes and hands-on practice to improve my cloud computing and data engineering skills. I do not use Azure for business or commercial purposes.

Recently, I received an unexpected Azure charge of USD 147.61. I was not aware that my learning activities could result in such a significant cost, and the charge was much higher than I anticipated.

I have already submitted a refund request through Azure Billing Support. However, the automated refund system indicated that my invoice was not eligible for an expedited refund, so I submitted a support ticket for manual review.

I would like to ask:

How long does it usually take for Microsoft to review and approve or reject an Azure refund request?

If the refund is approved, how many business days does it typically take for the money to be returned to my original Visa card?

Is there a reasonable chance of receiving a full or partial refund for unexpected Azure charges incurred solely for personal educational purposes?

Does Microsoft offer a one-time goodwill refund for individual learners who unintentionally incur unexpected Azure costs?

This unexpected charge is a significant financial burden for me as an individual learner. I sincerely hope Microsoft can consider my circumstances and provide assistance.

I would greatly appreciate any guidance or information about the refund process.

Thank you for your time and understanding.
