BAD CUSTOMER SERVICE - INTERCITY

I booked 4 tickets in October from Margate to Johannesburg in December 2019. I couldn't go anymore so I cancelled the tickets. This was in the beginning of December. I am still waiting for my refund, everything I phoned to follow up they promise to phone me back, but it never happens. I spoke a few times to Patricia but no luck. I will never recommend this bus service to anybody and will never make use of them again.
