cashiers neglegance

good day on friday the 7th of july went to shoprite money market to buy a bus ticket for intercape to pretoria from durban amanzimtoti, was helped by a lady called hlengiwe mkhize. I asked her can i have a ticket frm intercaoe departure at 9am at amanzimtoti south gate caltex garage to pretoria and the lady said there is no 9 am bus and then asked her to check for me if there is another time slots available and she then punched under amanzimtoti and found there is one for 8:15 am leaving by total garage amanzimtoti, i then agreed to that slot and she printed the ticket for me and she asked me to sign to check if the time is correct and arrival time to pretoria was okay with me then i signed. She then stapled the ticket to an intercape cover Then the followong morning on the 8th of july i went to the departure with the child i bought the ticket for , we waited n the intercity bus arrived and i looked away knowing i bought an intecape ticket and it left, now it was 8:26 i called intercape to check if the bus is late and the lady told me they dont have the person of the name on the tickect and they dont even have a bus departing at total garage and i told her how come cause i bought a ticket at shoprite and she then told m to check properly inside the tocket if the slip is written intercape , cause apparently shoprite has that tendency of using their cover for other bus tickects n to my suprise excactly the ticket was for intercity

Went back to shoprite money market to query on the matter , the lady that assisted me day before just told me to do an exchange, she doesnt evn remember how our conversation went and they called their admin manager she then called intercity to see if the can assist me with another slot and was told that it was a loss because i missed that time, i told them i ddnt the cashier gave me a wrong ticket and then they told me that shoprote has to sort the issue out. And their manager said there's nothing they can do and her name is Thobile Shandu , they then calked tgeir store manager Rodney Gcaba to the matter, i explained to him what also happenedand he then said who helped m i told him and that lady already was taken to another shop at my presence and they ddnt even wait for the matter to be resolved, so the store manager and the admin manager ended up saying im the one in the wrong cause i signed but i told them i signed knowing i bought the intercape bus ticket and only thing changed was the time slot i needed, i need this matter attended too because the humilated me and never see their cashier with any niglegence and i ended up buying another ticket because no one seemed to look into the matter and follow protocol
