Vr6 engine with bearing knock

Firstly false advertising Secondly sells fu*ked spares

I had purchased a vr6 engine from them on the 12th August 2021, as they were loading the engine in my van I noticed oil and water mixing and I asked them about it and was told they were washing the engine that's how there's water there and the motor is 100%, I took they word for it and left it at the workshop where my car is and they had called me a week later to let me know that the motor has a bearing knock and the head gasket is blown, I then contacted nmt and was advised to bring the engine back, as told the driver went with the engine to them and they had told the driver to take it back to the shop and the owner would come collect it, it's been 3 months and I still have the ****ed engine and no vehicle, they refuse to reply to me, I would NOT recommend that anyone buys their spares as they sell us ****
