Rude agent dropping call ubruptly

After an hour conversation the agent put the phone down in my ear when I enquired about the safety of giving my banking details. Her phone presence was unprofessional and u enthusiastic to start with but I decided to treat her kindly, she did not treat me well after all the information I provided for comprehensive car cover. I don't remember her name. Never treat a customer like this. I will be advising friends and family away from your company.
