Tradekey的金色会员的业务专员效果如何？

我们已经是tradekey的银色会员。想升级到金色会员，主要是看重这个所谓的drm, 直接关系经理，或者说是业务专员。据说“as your drm has the master data of all the buyers he will start calling all the buyers one by one for you and give the products proposals to them, and whoever buyers is interested in your products he will directly connect the buyers with you, which means you will only get live connect buyers from your drm.” 不知道有没有人用过这个服务，效果如何?我担心drm会为了完成任务而给出一堆不可靠的询盘而浪费我们的时间。 另外goldkey的seo效果好吗？我们没过seo。 谢谢。
