This phone number was once used for Logitech support, but it is no longer active as a Logitech phone number. When you call this number, you receive an automated message telling you that this number is no longer active.
The message then tells you that Logitech would be happy to provide support in another manner. It suggests going to Logitech's website and requesting phone support, which you can do by visiting the contact page.
Once there, you can select phone as your primary contact method. If you do, the website will give you a call to provide support with your Logitech product.
At that point, the automated message hangs up. The customer does not get any opportunity to speak to someone, get transferred to another line, enter a selection or any other decision. The call simply ends after providing its message.
A check of this number reveals that searching for it does not lead to any mentions of it on Logitech's page. Several results come up confirming that it was a Logitech number, but all of these come from third-party sites, not Logitech itself. One search result is for Logitech's website, but even it expressly points out that Logitech's page does not include this number.
I believe this is set up very well on the part of Logitech. It makes it clear right away that the customer has not made an error, and this was once a Logitech phone number. It does not waste the customer's time by offering unnecessary interactions. It provides an alternate solution that requires limited action on the customer's part. Going to the web might be an extra step, but as a tech company, Logitech's customers likely would have already been familiar and comfortable using their internet connection for information.
Most importantly, Logitech makes no effort to put this number out there and possibly confuse its customers. It does not advertise this number anywhere on its pages. If someone calls this number, it's because they've either called it several times in the past and it's the only number they remember for Logitech, or they're actively seeking out this number.
Obviously, I cannot recommend using this number for anything. Unless you need to be told the fastest way to reach the Logitech support team without looking it up online, there's nothing here that's of value to a consumer. All you'll get by calling is a waste of about 20 seconds and information you could have found online.
