I got a call from that number and I just blocked it. Question is...how do they get my phone number in the first place? I don't give it out to no one. Only one person knows my number and that's my boyfriend and/or family members.
Most of these call centers use automatic dialers that just call all numbers in sequence so they don't really "have" your number although they may log any numbers that get answered as good numbers to sell to other scammers.
