It seems that dell shows the status as shipped but doesn't actually do it at that time.

My order was expected to arrive between 29th-31st July but I received tracking details on 1st August and received order on 4th August.

Hi,

Sorry for not being able to respond to you in time. We're facing an unusual spike in volumes today, and we're only seeing your message now.

 I'm sorry to know about your order. Could you provide the Order # and the registered owner's name via direct message? I'll have it checked right away.
