I ordered a phone Xiaomi note 3 pro on June 6 and also paid for a DHL shipping which should not take more than 3 days to deliver.
I have written to inquire about the position of my order. All I got on each occasion is a computer generated reply telling me that someone will get in touch with me very shortly.

On my page on their website, my order is still processing.
It takes less than 5 seconds to accept payment and now it's taking more than 6 days to do the processing.
Is this a legitimate way of doing business or a fraud?.
My order number is 3325.
