Extremely bad service and not customer etiquette

I've ordered twice before from this company and on the last order I had forgotten to stop the subscription. On the 22nd of April 2020 I immediately after seeing the debit order has gone through I notified them for a refund. I was promised a refund within 8 - 10 working days. My refund of R867.50 has not been done to date, the company's consultant Massy has been giving me a run around on the matter.
