Shoprite Stinks of greed

I bought bus tickets from Shoprite(Intercape bus tickets) Vredenburg 2 on the 01/06/2020 to travel back home from Cape Town to Joburg.3 bus tickets for my fiance and 3yr old child to the value of just under R2500.I am unemployed and was assisted by good samaritans to buy the tickets.The tickets was for the 04/06/2020. The bus was scheduled to depart from Cape Town at 12:00. I was there on time and was informed by Intercape personnel that I require a permit to travel between provinces. I was not informed by Shoprite where I bought the tickets that I will need a permit.They just took my money and issue tickets without informing me about a permit.We have a 14 yr old daughter that needs us urgently at home in Gauteng.If we knew we suppose to have a permit, we could have made the necessary arrangements for a permit before going to the bus.We tried to made a complaint at Kraaifontein shoprite 2 ,but was told that it's not Shoprites problem.Intercape refer us to shoprite , and admit that it was Shoprite duty to inform us about the permit.We are now sitting on the street basically,with a 3yr old child and nowhere to go.
