Refund overdue by three months

I booked online accommodation on 29th October, 2020 only to be advised that my EFT of R980-00 failed. SafariNow sent several failed notifications to this effect and warnings that as there only only a few rooms left therefore my urgent attention was required. I went online again and this time they advised payment was successful. Later when my bank statement arrived I could see that both EFT's had gone through. I contacted SafariNow who agreed that I was due a refund and requested my bank details. despite numerous requests, the refund of R980-00 has not happened. i'll never book via SarfariNow again and caution others not to.
