Caller: I don't know

There was a slight delay when first answering the phone then I heard a click and an automated voice spoke telling me that my internet connection is going to be disconnected in 1/2 hour due to a modem issue and to press 1. I hung up at this stage due to the nature of the call. It was obviously a spam caller as my connection is fine and I have received no notification from my internet provider regarding any issues.
