Fraud

Good day everyone,this is my first time on hellopeter,my daugter bought a vehicle from a dealership,she bough its as is,but the cardealer scammed her,he never said the vehicle was a rebuild,the vehicle did not have a license,the paperwork was all outdated, the paper my daugter signed for the vehicle the registration on the paper doesn't match the vehicle's registration plates,the vehicle was a total wreck,she bought the vehicle on the saterday afternoon, as soon as she got home she was very disappointed withe the vehicle we contacted the dealer/owner to confirm we wil be refunding the car on Tuesday since the monday was a public holiday, the Tuesday morning we were at the dealership and the owner was very rude,he took the vehicle back and said if we refund the vehicle he would take 10%,which we agreed on,we then asked for some kind of proof that he would keep hus word on doing the refund,he got agitated and said if we dont trust him we should leaf everything and leave,we then left the vehicle there since it is a hazard to drive with(life threatening)and is not roadworthy,the owner said he'd to the payment it'll take 48hour,after this time i contacted him on watsapp and he admitted to being wrong for selling her this vehicle and admitted to have never tested or inspected the vehicle,I've got lots of evidence on our chats and voicenotes where he admits he was guilty, after a day he got realy rude,threatening me and blocked me,in the meantime I've hire a private investigator and is currently busy with the case,all he needed was fir my daughter to open a case at our police station a case of fraud,now the police said that we can not currently open a case since the paper says that its bought as is,but the paper where my daughter signed on the vehicle's registration doesn't even match the vehicle's registration,that is fraud alone right?please if anyone can give us anything to work on,the car dealer has the vehicle at the moment and refuses to refund my daughter's money,the vehicle was returned within three days...
