Not satisfied at all

I Sinoyolo Balelo, seek for help and impactive solution here is the scenario. On the 24th of May2024 I booked Apmwc bus ticket at Vaalgate Shoprite that was set to depart on the 24th of June 2024(20:00pm) from Johannesburg Park Station to Umtata Station on the 25th of June 2024. Due to Examination postponement reasons from my institution, I had to apply for date changes/reschedules so I went back to the Shoprite where I booked the ticket before the departure date or day arrives regarding the matter of changing the date. AT Shoprite I was that their system does not allow them to change dates, the only thing they can be able to do to help me is to cancel the ticket and refund me but there will be a penalty fee of R50.00 for ticket cancellation that is deducted from the amount I previously paid for my ticket . Meaning they will subtract R50.00 from R410.00 that I paid for my bus ticket and remaining balance will be R360. Unfortunately when they try execute their suggestion or perspective of canceling ticket and refund me, the available refund balance was R0.00 they did not proceed with that option of canceling a ticket and refund instead they called Apmwc company and Shoprite was told that there's nothing they can do on their side to help me, As Apmwc they will contact me as a passenger. Then days went by, still waiting for them to call me like they said but nothing from them, out of my confusion and stress because I see no progress and I'm being delayed I decides to call them by myself to make a follow-up.I called and reached them, they told me that they managed to cancel the ticket but they refund is in terms of voucher they don't do cash back refunds. So when I'm trying to use this voucher for booking another ticket I'm being told Computicket and Shoprite are not fami**** with this voucher thing that I'm given by this Apmwc Company and there Shoprite again calling Apmwc Company for clarification on how their voucher method works, Apmwc fail to provide concrete clarity. Shoprite and Computicket suggested that I go to where the bus supposed or setted to depart from and ask one of the Apmwc' s worker to help me on this matter, when I get to Park Station in Johhnesbeg and looking for those Apmwc buses and their offices they are not there when I ask around about them I found out that Apmwc Company was long back banned/evicted from Park Station. My contradiction is the still use Park Station as their point of departure. What I'm actually asking from you "Hello Peter" is to tell them to organize another trip or bus for me because this thing of their voucher is senseless to their co working shops or branches before 3rd of July 2024. Here is the cellphone number I used as a passenger's contact 0719480881 on the previous ticket but I'm no longer reachable on the above contact, they can or you reach me on the following numbers 0833168706 and 0824357396. Same destination(Umtata Station) same point of departure(Johannesburg Park Station).
