absa teaches its staff to be rude and belittle its clients

So i receive a call from absa AVP Services from an agent called mlungisi simphiwe masondo who was ridiculously rude to me. he called me and what i ask what the call is about he goes to say im asking him the same question over and over, he says i should rather read my email and message i will get answers there. and i ask him then if that was the case why call me then cause i would have just read the email, why is he calling me directly and refusing to explain what this call is about? hthe email sounded like they forcing me to take absa insurance and that i need to send them proof of cover, fine but in the end he asks if im happy with my current insurance which i totally am and would never change to absa cause they are not rude and treat thier clients with respect. i need to to understand f this is what Absa stands for? are your agents supposed to be rude to clients and is this how absa treats their clients? other banks care about thier clients and this was just awfull.
