Who called from 6128278974

Shows up as unknown on your caller ID, if you call the number back you receive no answer, not even voicemail. I would say it is a scam or some sort of telemarketing...Don't answer it and maybe they will quit calling.

I answered the call, heard a few seconds of background conversations, and then the caller hung up.

Received a call from them asking for my husband by his correct name, when I said he wasn't here, they asked for "Mrs. ....," when I said she wasn't here either and asked if I could take a message, he said "no" and hung up.

Same as above--a few seconds of conversation then hung up.  Any calls back just ring and ring and ring....
