I’m never buying another Nissan car-cheap

The cheap materials and cutting of corners has resulted in me driving a car that requires being jump started each time. They know what the problem is and they keep playing around what could be the problem. I lodged a complaint for a free battery replacement in July. They said they only replace faulty batteries nothing is wrong with the battery. In August the problem persisted after making me remove my tracking device. Now that I don’t want the unit any longer over a 7 month period of being jumpstarted. They are telling me I must replace the battery. They could have saved me gastric ulcers, increased heart rate, memorandums of explaining why I wasn’t at work on time etc in June not in Oct.
