Only communicates by telephone - I want details in writing

I used the app to request a quote, entering all the details asked in the online questionnaire. A person called me a few minutes later and asked me a number of security questions (he called me!) and then asked the same questions I just answered online. I asked for 2 quotes by e-mail, so I could compare with other insurers. I only received 1 quote. I reply to the e-mail quote asking for the 2nd quote and get an automated response asking me to call the call center. I just want the quote, not to talk to someone who will ask me the same stupid security questions and waste 10 minutes of my time during work hours. I do not do business on the telephone. Outsurance may record calls for their own protection, but I do not record my calls. I want to receive written confirmation of what I am told, so I have a record. Quite frankly I am getting tired of Outsurance's insistence only to communicate on the phone and may well take all my business elsewhere.
