Hi. On April 26th I bought a Sonos Roam SL through the online store. The order was invoiced on my card. For some reason, the product did not arrive at its destination in Portland. It arrived in Troutdale and, for no reason, returned to the sender on May 13. I've already sent Sonos a lot of emails and talked to two attendants of Sonos, with no solution. 

What else can I do to receive my product or get the cancellation and chargeback on my card?

Any suggestions?

Thank you for your attention
