WITS BURSARY OFFICE HAS NOT REFUNDED MY COMPANY

I have a bursary with my company to do my GDE at Wits.<br> I completed my course and had my graduation in December last year.<br> I have a refund balance of ~ R5000 on my student account.<br> I have tried contacting the bursary office via email and phone several times from last year September.<br> The bursary office does not respond to emails, neither do they reply to voicemails or answer phones.<br> This is unacceptable. How can Wits be regarded as a world class university when they can't even reply to a email!!! Interest is incurred on late fee payments, shouldn't it apply to Wits as well!!!!<br>
