Fees refund not received 5 Months later!!!

I couldn't complete my Higher Cert during the Nov/Dec 2017 Exam period due to a taxi strike that prevented me from accessing exam venue for my one module. Went to main campus and was eventually granted a second chance to write the exam during the May/June 2018 period. I ad to register the module and pay for it AGAIN. I did that, wrote my exam and passed it. Good news was that i could claim for a refund on my registration fee for that module. Went and followed the process and all was complete and submitted on the 27th of September 2018. The refund is supposed to take 21 working days so i was expecting my money at least during the month of October. Sent a follow up email in October and only received an automated response. 4 Months later, i get a Apologies for the delay, please attach your ID copy. from Tebogo Lamola @Student Accounts. To which i responded with my ID copy. 5 Months later, i am still waiting for my refund, my Certificate hasn't been delivered since August 2018 and no one responds to any emails. No one answers the phone when you call. This is really frustrating. Is there anywhere i can report this?????
