APM bus didn't pick us by Park Station

I bought a bus ticket on the 23 August from Shoprite cost R400 from Johannesburg park station to Idutywa. I went to park station on time when I get there, I look for APM offices but there was nothing. I ask the security to show me gate 1 and different security guard were telling me that APM is no longer using Johannesburg park station , I have to go to the main gate. I was so shocked but went there and I found many people standing there aswel waiting for bus. We receive a message saying APM apologize for inconvenience they are running late till 22:00 they sent a message saying we must make come back next day still next day same apologize. Last message said we have to email them for ticket voucher, I want my money back and I wish they can cancel this route at Shoprite because we will endup saying they are cruel aswell please Shoprite don't sell APM bus ticket. My ticket number is APWUWOA01
