Caller id says "BB Trading" and they ask for a person and if that person is not available they say "no message will call back later". They do not identify themselves or give any details about themselves.
Received a rude call...asking for my husband, when I asked where he was calling from or what he was calling about, he said "personal business." So I went a few rounds and he wouldn't disclose where he was calling from or what it was about, so I said, "Well, if you are calling for personal business, then you know his personal cell phone number and can call that." He didn't seem to like that. I just said thank you and hung up.
