They were my service provider since 2018 when i purchased my vehicle. All repairs and services were done by them. My last service and repair was for a timing chain. Job done and after 4700 km in 5 months my vehicle broke down again. On first inspection they said it was to do with a sprocket on timing chain. But 2 days later changed their diagnosis. My vehicle ended up on the s****yard. Needles to say my faith in the brand is -0 .
