landline dead for 12 days with no feedback what so ever

My parents landline has been dead for 12 days now, i raised this issue with telkom on the 13th, and have escalated this on the 17th ( a week ago today) WITH NO SUCCESS. i phoned two agents now and can you believe it, both of them gave me different feedback.

i have given my cell number and my fathers cell number i dont know how many times and guess what nothing has been conveyed to either of us, no call no sms no nothing.

i have to waste my time calling almost everyday to get feedback due to telkom incompetency

i called now to speak to a supervisor as enough is enough and i was told they all on training- WOW WHAT A JOKE
