How to log a fault

  • TENET maintains a service desk that responds at all times ("24 / 7 / 365").
  • To contact the service desk call 021 763 7147.
  • The TENET Site Number (TSN) is important for fault logging - it speeds the process of communication between the service desk and TENET's engineering staff. You can check the TSN number for any site on the graphs pages.
