Sold a house without full disclosure as per law

I bought a house through this company Without my knowledge. , I discovered the previous owners were hardened gangsters involved with drugs , weapons and ammunition. The agent Priscilla, was the sellers direct sister Which means she knew what was happening there The house also had hidden defects which they refused to fix The electrical DB board is completely messed up and needs replacement, after a month there tge geyser blew. Theres only one plug working in the house and the lights not working as per requirements I had an electrical inspector do a report and said the house is a fire hazard and should never have been sold Up to now , I've had endless problems in that house That woman license should be removed , if she even has one Firstly:..since it was her brother..there's the 'conflict of interst' issue at hand And that is exactly what happened!
