Hung up after i answered

At first I thought it was a hangup and was about to hang up myself when I heard this guy talking, so I missed the first part of his little speech. What I did catch was, he said he was calling in response to a survey I recently took online. Since I rarely fill out surveys and only for companies I know, I had a feeling this wasn't a real call. I said I had no idea what he was talking about and hung up.

Online survey response. Took no such survey. Hungup.

Received call around dinner time.  I did not answer the phone as it was a number I did not identify.
I'm reporting it to do not call list.

Rec'd a call from this number about a survey that I had taken and that he would like info about a job search.
Not only did i not take a survey ,i am retired.The caller would not take no for an answer so i hung up
