cancellation still not done after more than 21 day

after having a case number for my cancellation and having been ignored by telkom for 21 days according to their ridiculous and stupid procedure now they tell me that they have no record of this cancellation. How can this even be possible if i have the form of cancellation together with the cancellation case number. if they are *********** its not my problem. i will not pay for any extra billing as my period of 21 days has expired and they have done nothing as usual. i repeat i will not pay any bill they will just have to pay for it themselves. i have never in my life dealt with such *********** people and rude to as well. they never know anything. what is the purpose of having staff if they don't know what they are doing.I WANT THIS NIGHTMARE TO END NOW. and the people resposable for this is Tsholo Modibedi and all the staff of cancellation department. I ALSO WANT TO SPEAK TO A MANGER> THIS MUST STOP. I DO NOT WANT TO BE WITH TELKOM ANY LONGER.
