Please try the Contact Us options in the bottom right of this page: https://www.sonos.com/support

The only contact information on the page you are referring to, is the ceo e-mail. 

I will mail to him. 

There are other support options listed on that page

I think that depends on which country the OP is in. Their profile doesn't list it.

Purchased a couple products last week and received them a few days ago.  I followed the directions to initiate the return process but never received a link. I submitted a support ticket but did not get a response until days later.  When I did, they advised me to use the same link and still no label was generated.  When I checked back again, the products were listed as ineligible to return.

Has anyone received this runaround?
