Unreliable engines

So ive purchased an engine that costed me R9000 at this place called cartease. As i work as a driver for the argus media buying this engine was my back up plan incase the original engine gives in i have something to fall back on. After 2 months of buying this engine the original one ceased and i had the one installed that i purchased at cartease. After installation we had the car started up and water was gushing out of each hole that you can find. I was going back and forth with this people as it wasnt R1000 spent and ontop of that with showing proof of parts purchased and presenting invoices of R1200 worth of parts baught i get told its an untruth full invoice and made up. How does one spend R9000 on an engine and get told rhe invoice was ****. Anyway after going back and fourth with these people they then decided to take my car with engine and have a look to see what happening. 3 weeks later i get a call saying and whatsapp messages stating that according to the consumer law due to untruthfullness of invoices they can not repair nor refund this total. Im not interested in the money i want the R9000 engine that i baught to work and i swear to god. I havent driven a 1m with the engine. On my arrival to collect my car and broken engine i discovered that the gasket that came off the engine that i baught was worne out hence why water went through. This is my thing i call a spade a spade. Sell me somthing worth benifiting from as youve benifited from me. But if i should call this a *******. I would consider that an understatement. I will not leave this likely. This i will definitely take not just to the rest of social media but taking this further. I cannot stand to see someone going through what i did. Now im sitting with a car with no engine that was baught bramd new through the bank and is unable to work and lost my job through this aswell. The frustration and disappointment is unimaginable.
