Greyhound Refund

I booked a return trip from Johannesburg to Cape Town for May 14th and May 26th 2024. Three days after making the booking, I called the Greyhound customer service to inform them that I would like to cancel the trip and receive a full refund. On the call I was informed that the refund would take 6 months which I thought was odd but I didn't inquire further as I assumed this was standard for Greyhound. As instructed by the customer service consultant, I sent a follow-up email to confirm my banking details and proof of the booking. Since then I have sent numerous emails inquiring about the refund and have received no response. The refund has not reflected in my account nor have I received communication that its been processed.
