Yes we get a lot of those also from "your internet/phone provider" we never respond to recorded messages except to block number. When they don't use our name (or if mispronounced) we ask "Who do you think you are calling?" which stumps them. When they say: "This is..." we just reply: "No it isn't you are a scam call centre in India" and put the phone down and block number.
