BAD REMANUFACTURED ENGINE

I got a new engine from Remtec Superior engine solutions on 17 August 2022 invoice was paid R52900.00, and the engine Ford Ranger 3.2 was sent to Johannesburg. The engine was not working properly the oil pump was not working, after 8 days of the phone call and Remtec send a person out to inspect the engine and said the oil pump was not working, two days later a new engine was sent and now its the same problem whit the second engine. Spoken to Remtac and was told that they have contacted the garage and it is now 28 days later and still no car running. Every day I am using uber and cost me R700.00 per day. It seems that there is no proper response from Remtec Premium Engine Solutions. I am at the end of my rope now. I need my car fixed urgent or they must supply me with a car till it's been fixed. Two new engines and both are faulty. The man that was spoken to Koos at have not come back to me and does not answer his phone now.
