Poor Service/Workmanship Nissan

I would prefer not rating this business at all. I bought a Nissan NP300 end of October 2018 at BB Sinoville Nissan. Bakkie went back in November 2018 for about 3 weeks after I complained about the noise inside the bakkie and the engine. I received bakkie back and Engine was still not fixed. Bakkie went back in November for a second time for another 2 or 3 weeks for the engine problem. I was assured the problem was sorted as they fixed the Injectors for the second time. Had the bakkie 4 days same problem. In December I contacted manager from Nissan BB and he said he will sort out with his workshop. Clearly those workshop guys are clueless with motors. Then Jaco never came back to me. I logged a call at Head office Nissan to investigate. This guys got me mixed up with another client. Poor service yet again. Nissan SA basically did nothing for me. Bakkie was collected in January. Bakkie was at Nissan again 3 weeks close to 4. Waiting for a ECU box. Poor service yet again!!! Got the bakkie back yesterday the 15 February 2019 bakkie still doing the same. Sick and tired of BB Sinoville Nissan. Would not recommend this service or store to anyone. Highly annoid. Always wanted a bakkie. Thanks Nissan you destroyd that wish of mine!!!!
