Disgusting telemarketing client interaction.

I have just received a marketing call from Kenneth of Quality Quotes from the number ***. When I started to say, "Thank you, but I'm not interested," he rudely responded with, "what are you thanking me for?" I cancelled the call and he immediately phoned me again and my partner answered the phone and listened to what he was saying before replying, "No thank you, not interested." To which Kenneth then said, "Oh, so you're not interested in getting money?" My partner cancelled the call. Kenneth then called back a third time, but then cancelled the call as I answered. Is this how DotSure wants to be represented to the public? From this experience, I will most definitely not be using dotsure and if I do not get an apology, I will be letting my social media followers know about my interaction with Dotsure/Quality Quote.
