scam call

Asian caller said she was calling from a back brace company and understood I had back problems.  She was calling from Atlanta she said after I pressed her for her location but it was only 8:15a in Arizona where I live waking me from a sound sleep.  I told her I was on the Do Not Call List and it was only 8:15a and she had woken me. She said she still wanted to know if I had back problems. Really?  I hung up on her.
