****** by Telkom

I took a contract with Telkom in May 2022 and the agreement was that I will pay them R315 per month and to my surprise the first bill that I received end of the same was R899 . So I called to enquire about it and I was told that the person who was assisting me with the contract added some things with out telling me that is why my bill was R899. Immediately I stopped using that sim card which they said it's got added things and they said they are investigating it is a dispute and from there I didn't hear anything from them about the disputed case but the bill keeps on going up from R899 to R6000 and because I refuse to pay for something that I did not agreed on they now blacklisted me .I really feel like I'm being ****med by Telkom and I don't think Is fair what they are doing. Hello Peter please help me.
