High and mighty support operator wont assist me

So Vodacom Fibre did something on our line after which our connection to the data logger on our solar inverter simply will not work. I called support and a lady tried to help me by doing something re the encryption but it didnt work. I called back only to be told its not Vodacoms problem... even though I can connect via a data hotspot, just not fibre. The lady refused to help me because she said its not vodacoms problem.. it is definitely vodacoms problem and I want it fixed.
