Bought electricity on FNB. Got the usual message but being half asleep I entered the string of numbers where it says 'key change token 1'. No idea what that is but something momentarily changed on the display.
Then tried the actual recharge number and was rejected. Tried the 'key change token 2' number. Display momentarily changed again. Tried the recharge number and rejected.
Bought more electricity. New number not recharging either...rejected. Any idea what's going on or what those key change tokens are?
