Hung up straight away. Already reported as a scam by other services

I answered the call and could hear the background of a call centre.
"Hello Wendy" - I'm a guy
"Yep this is Wendy"
"This is Harry from Solar company How you going?
"I'm great"
I hung up.

Unanswered. Did not return call. Assume spam

Called but never left a message.

the caller from this number stated he was a real estate agent. I told him I was not interested and hung up.

Called but did not tell me where they were calling from after being asked twice. Delayed responses and lost of background noise so assuming a scam.

Called twice and hung up twice. Thinking scam or pest
