Eagle Liner is the worst ever

In early March this year I booked a bus for my sister through Computicket for Eagle Liner. The bus was supposed to leave East London to Grahamstown at 16h30. The bus arrived late and was faulty. By 21h30 the bus had still not left and the bus driver couldn't give us information about what would happen. My sister ended up not taking the bus as she would get to Grahamstown really late and it wouldn't be safe for her to walk to her res. The following day I called their offices, I was helped by Idah, who indicated that I would be refunded the money after 7 business days. That was on 10 March 2020, today is 13 August 2020 and I've still not received my refund. I've sent emails but I don't get a response. I've called and both Idah and Yolanda have indicated that they will check with the Finance Manager and get back to me, they don't. It's honestly so frustrating. This has to be thee worst experience and customer service I've ever received.
