Extremely bad attitude from the service follow up

A person from Toyota South Africa phones me in order to follow up how my service went. The lady asks to speak to my wife, I politly asked why as to which I informed her that I am the owner and the person that took the car in for services. She asked the second time to which I rep**** the same. The lady then just slammed the phone in my ear. So I went from no interaction whatever with Toyota to angry within literally less than a minute. So unfortunately my reply with regards to my satisfaction with Toyota service will in the future not be as good as it has been.
