Caller ID name was the same as the telephone number. Called suspiciously soon after a call from 609-961-6631, whose Caller ID name was also just the number. This is the US Independence Day holiday (7/4/2017), so this is quite out of line for a legitimate business.
As far as I'm concerned I believe this is NOT Heifer. I could not find anything to link this number with them. I believe it is a scammer/phisher. All legit business callers would leave a message of some sort and not call several times/days in a week and just hang up. I have now blocked this number. By the way Heifer is a great organization and I would hate to see it be tarnished by some seedy people!
