Hi Marina,

I understand that you were having some issues with a course you recently signed up for and was requesting for refund. I’d like to understand the nature of the problem you experienced so we can continue to improve our training services.

If you don’t mind elaborating on the problem with more details, it will be greatly appreciated.
