Rude and unhelpful agent

I've had issues with emails not coming through to me and have called Outsurance numerous times over the last 2 weeks so that I can test if the mails are getting blocked on my side. Today I called to confirm that the issue was not on my side but on theirs, but she did not want to listen to what I tried to tell her, acted like she knew what was wrong without giving me a chance to explain what we did last week already. She kept telling me to be quiet when I tried telling her that she does not know what my issue is and that it is not resolved. Eventually I asked if I can speak to someone else because I felt I was wasting my time trying to talk to her. She then got very agressive and asked who I would like to speak to. I then told her that I want to speak to anyone with a better attitude than hers, meaning she must transfer me. She then put the phone down in my ear. If she listened and looked at my log for the last two weeks, she whould see that I actually know what I am talking about. I called again and an extremely helpful lady (Lucia Magakgala) listened to my query and confirmed that the email issue is not resolved. This was the first time I got bad service from Outsurance.
