Phone etiquette with clients

Iv been struggling with my internet service for a few weeks now so yesterday 10/09/2020 I resorted to calling the call center to find out what could possibly be the cause... my call was picked up by a Thabile Radebe. The young lady was very rude or rather yet her response or questions with regards to my enquiry were uncalled for... i was asked if I know how to search for network on my phone? Disregarding the statement I made telling her my attempts at regaining network, then was later ask “so you DEMANDING I log a case for you”? I don’t know if this is how they are taught during their training but I felt utterly disrespected especially because I was calm and patient with her...! I can’t keep being without internet service and at the same damn time every day.
