This number States it is the "Heart Research Charity" ??? BUT I doubt this is true!!

Unsolicited call. 3 rings then to voice mail. No message. Definitely nuisance, possibly fraudulent. I would not deal with them if they won't identify themselves. Even if genuine they will be contract callers who get paid out of any donation you might make and little goes to the charity they claim to represent.

I don't answer it, but I have received one, sometimes two calls every day for the last month

Caller: Heart Research Institue

I answered, all I heard is some CREEP breathing into the phone then hanging up.
They dial at 7:40pm at night.

Waste of time nusiance spam scam calls.

I dont answer numbers i dont know. Just block them on your phone !

i have received a few calls from them don't answer unknown numbers, if they want to talk to they will leave a message, if they are too dumb to do that they are too dumb for me to waste my time on them

Caller: Heart Research Institute

Claimed to be calling on behalf of the Heart Research Institute. They didn't get through their whole spiel as I mentioned that I was likely not interested. They were pleasant enough so I don't think it's fraudulent or a scam.
