Bad quality workmanship, serving my Vehicle at Rosebank Suzuki

I have always serviced my Suzuki Jimmy at the Northcliff Dealership, and never had issues. Suzuki Rosebank opened in December of 2022 and thought that it being closer, I would try put their service centre. Twice in a row, I had to take my vehicle back to the service centre, this morning, when you used the vehicle, same noise persist. Either the quality of technicians and bad or the vehicle is a problem. I need Suzuki to resolve this issue ASAP, and will be reporting this to Suzuki SA
