Caller type: Survey
The date was Monday, October 7, 2019. He said he was conducting an important survey. I thought it was odd that he was calling so late, past 8:45 p.m. He spoke fast, not giving me a chance to speak. Finally, I said I did not want to take part in the survey. Instead of respecting my answer he spoke over me and said it was very important. Again I said, "Sorry, but I'm not interested in participating" He objected again, and I ended up having to say no, more than four times. He still persisted and finally I said, "no I don't want to participate" and hung up before he was able to say anymore. I almost expected him to call back immediately. I would not trust anyone who is that inconsiderate and pushy concerning a "survey".
