He suggested that I can go home then I come in the morning or wait them till they back, I left police station to came back in the morning, then on the 09/07/2017 I went to open the case as case no. 36/07/2017, I return the car at cape town airport. Later they send me a quote it R87411.16 I need to pay them according with them they said I breach contract. Where exactly I breach contract here?
