No service received after money paid and they are refusing to refund

I paid for my course on the 20th of July 2024 and have still not received any logins. I have chased this every week and every week I am told I will receive my logins. It has been 3 months now and i am still chasing. I wouldn’t recommend using this company as I have also been told I can’t receive a refund due to the course being purchased on promotion. So now I am R2000 down and haven’t received the service I’ve paid for.
