Who are we supposed to get answered from when the people hired to assist us get annoyed?

<p>I called Nedbank insurance/Homeloan department to request assistance on an issue that has been troubling my parents for the past few months.</p> <p>After being transfered amongst diffrent departments i spoke to a lady by the name Lusanda, i asked her a few questions to understand the process that was going on. She ounded very irritated on the call, she kept cutting me in between asking questions and would rudely give her remark. when i evntually asked her to transfer my call she made a "eih" sigh in the end and then further transfered my call, being Zulu i understood exactly what that sigh meant.</p> <p>Its a pity you get people like this in between calls as Bongi from Durban and Vershika had been very polite and kind. </p> <p> </p>
