Scam robocall

Answered a call on my landline. It took a good couple of seconds for the person on the other end to respond (1st sign of a scam call, delay routing the call to a person.) A male, with an accent (Pakistani or Indian), said that he believed he was speaking to & he badly mispronounced my surname (2nd sign of a scam call). I said that there was no-one here by that name so the caller hung up (3rd sign of a scam call).
