Person from a busy call center trying to tell me that I am getting ventilation fan upgrades. Yawned during his speech and I said that he must be tired and should get some rest..

Lol, he just went silent and hung up after a few seconds :)

Caller: Scam call about fan upgrades

Do not give any information to these scammers. Block number immediately

I just said nothing when I answered this call. After few seconds they hund up! These calls are usually voice activated.
