Who called from 6474842681

We get a call from this number at least 3-4 times a week. There is nobody on the line and no recording. It is silent for about 15 seconds and disconnects

We receive calls from this # a couple of times a week.  No answer, just hang up after a few seconds.  I called the # twice today and both calls were answered; the first person just answered hello and I asked to be taken off their call list; the second time I called (forgot to ask the first person) the person identified themselves with Sovereign and I asked what they do she said they are a large investment company out of Canada.  I asked them to remove us from their call list.  We shall see.

They called and sounded like a computer I told her not to call back and she says why right as I hung up on her

Blocked it.

called them back to see who it was.  said they wanted to send me an investors kit.  said, "no thank you" hung up & blocked them.
