Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Logitech is a Swiss company with branches in Newark and in California - but they do have a customer service number, which seems not to be toll-free, at
and there are other means of contact for specific products or product branches/groups, if you go to this page
and click on the triple-line icon roughly to the upper right of the page.
Logitech has a peculiarity that many find off-putting, in the US at least: they do not service their products (except perhaps for defects-under-warranty.) Be prepared for this, if your Logitech product is out of its warranty coverage period.
Is there anything specific I can advise or help you with? if so, please mention it. Thanks.
