It normally means that the item has been dispatched but ‘normally’ you get a message from Sonos and the courier!  What is the order status in www.sonos.com?

Thanks for the update I went on to track order but it says no orders 

Did you receive an email confirming the order?  If so click on the order number and it should give an update on any order that has yet to be processed - although it’s confusing why the money has been taken?  Have you tried calling the Sales help line https://www.sonos.com/en-gb/contact 

Thanks for letting me know I will click on the order email to find out if the order is processed
