Non service delivery on fiber line in South Hills

No internet service from 26th September to 29 September. Again on October 11th and 12th. Now, no service since Saturday 15th October, mine is still off. I have spoken to 7 different helpdesk agents and each has given a different story and a different reference number. After 20 minutes on the phone with agent number 5, I asked if I could receive a call back since my air time was finish, the agent informed me that they are not allowed to make out going calls. I have names and surnames and dates and times. Helpdesk agent Brian told me on Tuesday at 12h00, that it was still early and the technicians are busy, I should wait. and then put the call on silent until I dropped the call. Telkom as a fiber service provider should is the pits. and month-end they expect their invoices to paid in full.
