Beittling another insurance comapny

Got a Phone call from a Discovery Insure consultant this morning, all was fine until he as who my current motor insurance was with and laughs and said they not a real insurance, and then continues to ask for my information, so that he can quote me on a insurance policy, as the call continues he keeps on belittling the company I'm insurance with, I was not happy with this at all and ask him directing why he is doing so, and he told me he not he is comparing the benefits of my needs, no where was the talk about what type of cover I was looking for or the benefits of my current insurance was mention. I also asked as where he got my contact information the call came to a quick stop and was ended
