Didn't receive my refund for a concert THEY cancelled

I purchased 3 tickets for the burna boy concert in September. The concert was cancelled and I immediately requested for my refund of R1500 to be returned. The consultant Dikeledi continuously **** to me saying that my refund will reflect within 7 working days. It is now 35 days later and the money has still not reflected. But I have been using my airtime and data to continuously try to get ahold of them to get my refund. Dikeledi has been ignoring my emails since 6 October.
