求翻译：客户（S300，WDD2211541A3054884）4月25日到店抱怨车辆行驶到坡路时，车身有异响。经我司技术人员路试，未发现异常响声。4月28日，客户到店反映车辆后顶棚有异响，但经我司技术人员检测并路试后，未发现有异响。6月17日，客户再一次来到我司反映车辆有异响，我司技术人员对其车辆车顶内衬进行了相关调整。经路试，车辆无异常响声。6月22日，客户再次到店抱怨其车辆右后部车顶在行驶到坡路时有异响，特别是在早晨或车停放一段时间。次日清晨，我司技术人员陪同客户一起进行了路试，发现车辆在行驶一段坡路时，转向过程中，偶有响声。但之后，就不再出现此响声。我司技术人员对其顶棚进行了调整，由于客户当日着急离厂办事，未能进行路试。次日，客户打电话抱怨车辆还有异响，我司已发送TIPS，现客户表示不满并找到了“中国质量万里行”进行投诉。为了能尽快解决客户的不满，希望贵部能够给予我司技术上的支持，谢谢！是什么意思？
