Incompotence

Since 30 april there was a contract out on my name, I sent thru documentation and according to the individuals I spoke to it was cancelled off my name. nou I receive sms messages threatening me that my services will be cut if I don't pay the cancellation fee. no one has contacted me since the last time I heard it was resolved, which was months ago. now calling in and asking what is the problem no one can give me answers, how can a resolved query or problem reopen? why cant Telkom phone me and discuss this and explain what the problem is? why send me sms's that my services will be cut if the problem is clearly on Telkom side?
