Poor service nd very bad customer care

On the 20th of January I booked a ticket for my daughter who is a student at Unirvesity of Johannesburg,the ticket was from Bizana to JHB bt due to NSfas delays she couldn't travel so I had to cancel the ticket.The trip date was gonna be 26th of Same month so I contacted them on whatsapp because their phone numbers doesn't work.on the 24th January I got hold of them on whatsapp,they took all my details nd banking details,screenshoted for me that the refund is done nd the money will be in my account within 15 to 20 working days bt all has passed still no money,I contacted them again they asked me ticket number I gave,agent told me it's nt done when I asked what is nt done ,is it the claim or the EFT they don't answer anymore the keep blue ticking me nd ignore,I tried sending email to their customer care the email is invalid so I urge all the victims of this company to get together nd take the legal action against them because they r totally ****ming the people nd they need to be published people must stop using their busses m so passed off
