You're making it difficult for me to do business with you

It is not the first time I approached MiWay for comprehensive house and vehicle insurance quote. My frustration is that everything seemingly needs to be done over the phone. When the sales agent called me the first time on a Saturday morning I requested him to send me an email that I can present all my details per reply mail, but I got the standard answer of 'I don't have access to email'. I asked to be called back at a certain time, but needless to say I didn't get the call at requested time. I then got calls all hours of the day, in business and outside business hours, when I'm busy and therefore not taking the call.
