Poor poor ****-like service from adidas

I made an order with adidas on 17 April, I got an email confirming this order on 18th with a tracking number. To my surprise the courier company says Adidas did not send any items and merely created a way bill. Meanwhile the Adidas app says the item is on its way. After about 4 calls and emails to Adidas, there is absolutely no word from them on exactly where the order is or what has happened to it. That's so appalling...and from the reviews I am seeing here , it's shocking that a supposed big company like Adidas has no customers oriented culture....1 of out star from over a thousand customers? That's is a shocker....you'd assume you dealing with some **** company.... Infact one of the customer service actually insist that I have to wait 10 days when infact the Adidas postal policy says it 3 to 6 days....I can't believe that in this day and age you have a company as big as Adidas so ill managed and with zero customer oriented culture...I should have stayed with Nike and Puma....this service is nauseating.
