Who called from 5204680411

Same as above - several calls.  Did not answer

Caller asked if I was Ms. A-------------.  I said, why who are you?  She said Ann (lots of noise in background).  Ann proceeded to tell me that their records showed that I had my security system install 3 years ago.  She then said were their records correct.  I told her it was none of her business and hung-up.  TOTAL SCAM

wanting credit card information. Do not answer this call

not answered who is it??

When I answered with just "Hello"  There was no response.  I repeated it 3 times, but still no response----just an open line.
