Operator cuts call on me

So I have been having issues with my router from last week. So yesterday 22/08/23 at 4pm I called in and was assisted by a female operator as I could not get her name due to the line been so poor I cannot identify her. While talking about my problem which is ongoing she rudely cut the call on me. I was beginning to get irritated with her cause she could not understand the situation I was in with the WIFI connection. When I asked to speak to her manager she says that the manager will tell me the exact same thing she just said. I am paying for a service monthly and her putting the phone down in my ear is unacceptable. I called from Sparks Road, Durban area.
