Worst experience ever

Contacted them after my vivaro turbo failed and had oil leaks, asked them to overview and replace engine and turbo. R33500 later and it is exactly the same. The amount paid was for work done and vehicle towing and replacing parts after it kept failing. Bolts are loose, cross threaded, have invoices and photos to proof. Does not honor warranty given ( 10000km) broken down 3 times in 2000km. Always has a clever explanation for everything that goes wrong, never owns up to mistakes. Poor workmanship and even worse work ethic
