迪亚天天超市员工服务态度太差了，怎么投诉啊？

先找店长。不行就打消协电话。

直接去消费者协会投诉啊

广发对他负面的帖子是最有效的投诉！！！

没听过啊。

严格地讲，“迪亚天天”这种商店的业态并不是“超市”（super market）而是“hard discount”（某些网友所说的“廉价折扣店”是比较正确的理解）。所谓“hard discount”，是家乐福集团拥有的一种零售业态。根据该公司官方网站的说明，其基本定义为：

Our hard discount stores offer a reduced range at discount prices – around 20% lower than major brands – in su***ce areas ranging from 200 to 1,000 sq.m for Dia stores with a parking lot. The range mainly comprises Dia-branded food products plus a small selection of established, major brand items. The group’s hard discount stores have extensive expertise in the retailing of fruit and vegetables, offering a range of quality fresh products at attractive prices.
