rate: 50Unable to register for warranty because there is no serial number.
Item has been received and is working. However unable to register for warranty because there is no serial number on the product.
Tried to ask Logitech for help to locate serial number. Much time wasted going round and round. Eventually managed to find the hyperlink to input my request. However when I clicked "sent", error message "OOPS We can't seem to find the page you're looking for." Logitech's customer service is non-existent.Jun 06, 2019
