Damelin Disappointment

I am very sad with the service I have received from Damelin. I had registered with them in January this year for a diploma in IT as a part time student however they could not offer the course as a result I asked for a refund of the R500 I had paid towards the deposit in March 2018 as of this moment i have never received my money and not even a single response to my emails from the finance. The campus I had registered with is Damelin Centurion
