Called, answered and they asked about duct cleaning. Said, "No thanks". Then they called immediately back and said "Not interested! Please do not call me again!" Then they called twice more! Seems very shady.
They called me so many time. The person's name is Sam and is for duct cleaning. I told him I'm not interested; take me off the calling list. He said ok, but still call me from time to time.
They've called many times. Most of the time, I've "missed the call" (I never heard it ring, but just saw a notification).
This time, I answered the call, and the minute I did, I received some jumbled speech and then the user pressed 5 5 from what I could tell. Then the call was over. I rebooted my phone after that and blocked the caller.
