Unresolved refund request.

I am so frustrated, disappointed and angry about the treatment I have received from the finance department since trying to retrieve my refund. It has been 3 months of back and forth with the finance department. I overpaid for my school fees back in February before I got feedback of a successful credit for one of my modules. I then proceeded to request for a refund however have been given the run around or blantantly ignored each time even through means of tactics such as getting a 'closed ticket' email even when it isn't the official closed ticket email. I'm tired. My experience studying there has been great except for dealing with the incompetence of the finance department. I have sent all relevant documents with no satisfactory outcome to date. I have been too patient. I just want my money back.
