I need a refund, computicket is disorganized

I booked a bus ticket ( Ref number B00HE2KX) online from Pretoria to Durban for the 28th, unfortunately I had to cancel my trip, I called Computicket on the 27th to cancel the ticket, I was told to go to Intercape as they are the ones who can help me. I went to Big Sky (Intercape) they told me to call computicket as they are the ones who can give me a refund. I called computicket again, the guy told me that I need a cancellation number from Intercape, told him I don't have it as I wasn't told about it. Well he called Intercape and a lady by the name of Mariska helped cancel my ticket and gave me this number A*** 2948, then I was told to go to any Shoprite or Checkers for a refund. I went to Shoprite Essellen Street, Pretoria and I was told that they are offline so they can't help me. On Saturday I went to Checkers Hillcrest and the ladies there could 't help me as they were getting an error message saying "Request Failed P**** Error". We called Computicket and the consultant kept us on hold from 19:20 until 20:00 and the store was closing, we had to drop the call.

I'm quite disappointed by the treatment I'm getting from you as your call centre numbers are always busy I don't get through.
