Telkom bad service

What a disappointing service I got from Telkom that made me to cancel the contract I had. From. The beginning of the journey, they gave me two contracts instead of one which took three months to convince them to remove the second contract. The current contract is had also started failing when they started billing me twice without any notification. It took three for them to tell me why the bill came and no further communication. Now when I decide to terminate the contract they still bill me for canceling after the whole dilemma of no satisfaction resolution of my billing. What a first and last experience that I went through.
