Who called from 3237478455

I got a call from this number at 1:37 pm August 20.  No message was left.  No idea who this is.

I have received 3 calls from this number in the last hour and ten minutes, but no voicemail was left so I don't think it is anyone I know. Putting on my blocked caller list.

Person called and left message just calling name on answering machine, as if they were playing a game and laughing was being heard in the background.  I Will report number and company name to authority!

Called back and said they could reduce my energy bill. Probably solar

Some turkey called and mentioned a 'HERO" programme regarding windows and outside paint to save energy. Told him to shove it and hung up!
