Who called from 2162421321

They keep calling my work number.

Calls. I say hello, she says hello. Dead air. I say hello again.  She justs sits there listening in!!!
Then keeps calling every 2 minutes!

4 calls today. Started around noon and ended around 1pm, eastern. Messagws were left. No words, just breathing.  I added this number to automatically reject in the future.

Had received a call from this number.  The lady mispronounced my name.  The lady said she was calling me about a skin product that I had called about (which I didn't call).  I told her I have no idea what she was talking about. Three (3) times I asked what company she was with and she would only say "It's a skin care" and 3 times told her I did not know what she was talking about.  Finally I had to hang up on her.

Same thing three calls in a row, one vcml with chatter, I will block number
