Got the same message as a robocall. Pressed 2 as instructed to be removed from the list. Hope that works. They use the phrae, "Sone from your number requested information," to make it appear to the FCC, that it is a legitimate call. I have never requested information about a back or knee brace. I'm also reporting it to: https://consumercomplaints.fcc.gov/hc/en-us - Press the phone icon and you will be taken to the phone complain page. Can't post that link, as it issues a case number that will be unique to each person. You can also register as a user of the site and log in to see reports.
