Several Fibernetics numbers (at least 2 Freephoneline and 1 Fongo Mobile) number are unable to be reached by Toronto Hydro. They get a busy signal.
Incoming call is not reached by Fibernetics' network.
You can test by try forcing a callback from 4165428000 (dial 6,0,1 and then your phone number followed by #).
Or you can ask a rep to call your FPL or Fongo Mobile number to test.
This may be an issue for those being contacted by Toronto Hydro after submitting tier rate plan change requests.
