14 months later and still awaiting a refund for a sim card that did not work

I ordered two Rain sim cards in December 2019. The one worked, and the other one didn't. I continuously contacted your call centre and sent numerous e-mails, but with no luck. I then started to converse with your employees via Facebook Messenger, however with each day that passed by, I had to re-explain my issue. This has been going on since January 2020, and is yet to be resolved.

I ultimately cancelled the one sim card that would not work, and that Rain was unable to assist me with, therefore I am requesting a refund of R500 for the two months that I had the sim card that did not work.
