Never ever buy from Manic auto parts they are liers and sell broken goods

I bought a "complete engine" and paid R13 000 cash the guy told me it was plug and play and promised that the engine is 100% and that i have a 7 day money back garentee Got my mechanic to fit the engine and found out that theres no timing chain and that the head and cams are completely broken Now when i call them they tell me that im lying and wont give my money back They are liers and stole R13 000 from me and wont refund me at all Most unprofessional business in Pretoria and they are steeling peoples money and giving them broken goods
