Got the same issue as the other comments. I picked up, no one on the line and it hung up.
When i called back to the number, it says it is FIDO trying to reach me to propose offers. They mention that they might callback but you can select to be removed to their solicitation list ( can take up to 14 days from the message)
This number has been constantly calling me every 2 days. I have awnsered once and the line shut off immediately. I live in Canada and it is unusual for me to recieve US calls. I’m assuming it is some kind of scam or spam.
