Very bad shopping site. Review on Aliexpress

As we know E-commerce shopping sites has been growing among the peoples who love to shop sitting at home and office. I have been exploring on world wide web, as I came across AliExpress.com with variety of product to offer to its customer. Thought the products looks good and the price are reasonable, so I order memory card and Bluetooth headphone from there shopping site. After ordering it mentioned that the product will take 2 month to be delivered to my postal code through china mail. I didn't got any details regarding the shipment and its tracking to track my product where it reached till date, One of the most worst aspect of this shopping site. Its been more then 2 month, I can not track my product not it has reached to my address. Customer Service is one of the worst, When ever I tried to call them its either busy or they put me in hold by saying we are looking into your matter, Which I never expect from such a known shopping site. Product quality is good but not excellent with the price range they are offering. Website interface is very attractive and easy to browse and operate, searching product is very easy although with relevant key. AliExpress.com app is easy to install in different operating system with minimal system requirement for installation. Reliability of the product cannot be said until I receive the product. Even thought all these negative happening, I am hoping the product is reliable and last long as it say in its product information.
