Cold caller hung up on me

Hi. I have just received a call from someone at discovery trying to sell me car and home insurance. I expressed very clearly that I am not interested and that I am happy with my current insurer. This caller persisted and continued to question me about my current insurance. She eventually just hung up without saying anything. If you’re going to inconvenience me with a call like this, you do not get to have such a stinking attitude, get annoyed and hang up on me. This was completely unprofessional. I am already a discovery client.
