Condescending and Disrespectful

I received an sms from VW FS Offering insurance cover, at the end it said FSP A&G. It did not click to me at that point that A&G is actually Auto and General. I responded "Yes" to the sms to get a quote. A consultant by the name of "Shivanie Naidoo" and when I heard her mention Auto & General I expressed my reservations based of the word of mouth, and she explained that they don't assess the claims are just one of their partners. I asked her to call me back tomorrow after I do a research on the claims experience for VW and Auto and General. She started laughing loudly and I stopped speaking and asked why she is laughing at me while I'm speaking to her, she said it's because I am not giving her a chance to explain. I then asked her to explain, she explained the same thing she explained earlier, I told her that I understand what she is explaining but that still does not justify why she would laugh while I am speaking. I told her I find this rude and disrespectful, she said she finds the fact that I am not giving her a chance rude and disrespectful. I asked for her TL she said he is not available. This is a summery of what happened, I told her the conversation is recorded and she was fine with that, so I have attached the recording. I have never been so disrespected as a prospective client in my life.She was so rude and condescending. Is VW and A&G so rich that their staff have no care for Treating the client fairly and respectfully? She wanted to bully me into continuing without doing my research, why would she be so rude just because as a consumer I want to make an informed decision?If this is how the sales experience is, what is the claim experience like?I find this treatment so offensive, I am shocked!!
