Romaith online ********* practices

I ordered a smart watch from the above online store and I received the watch but it was nothing as advertised or as the video or pictures they had on the website . Nothing had been done from their side and they want to give me a discount on my next purchase. I would never purchase from them again and the way they operate is *********, they got the money for the item and now me having the item which is nothing like I ordered is my problem.
