Very poor and frustrating customer support

The after sales and technical services at Zoom Fibre and Flex prepaid are frastrating and very very poor. There is a agent by the name of Keleabetswe who is very arrogant, rude, impatient and ***********, he is clearly not helpful and poorly trained on the systems. Is there perhaps someone that can assist me with a contact number of a capable person at Zoom Fibre that can please assist with my "connected no internet access issues" cause the WhatsApp customer support is very frastrating and time wasting.
