If you're getting unwanted robocalls on your landline from Spectrum, there are a few things you can do to stop them.
First, you can sign up for the National Do Not Call Registry. This will stop sales calls from real companies from reaching your phone. You can register online or by calling 1-888-382-1222 from the phone you want to register.
Next, you can block specific numbers that are repeatedly calling you with Spectrum's Selective Call Rejection feature. To do this, log in to your account online and go to the Caller ID & Call Blocking section under Phone Features. From here, you can add up to 12 numbers to your call rejection list.
Finally, if you're still getting robocalls after taking these measures, you can file a complaint with the Federal Trade Commission (FTC). The FTC takes complaints about illegal robocalls and works to track down the source of the calls and stop them. You can file a complaint online or by calling 1-877-382-4357.
