Incorrect, ********** billing from Telkom Mobile

I have a cellphone contract with Telkom, around September I had a fight with my sister for the Telkom bill that I received thinking that she was the one miss using the data and topping up with out my knowledge for the ********** 124, later to find out that she was not the one doing that Telkom was, cause they are now doing it on my other number ********** 680 and they started this since May cause they never send the break down invoice. I opened a case with them on October regarding this, and they have not called me, they just told their operator to close the case and sent me an email I don't understand and I have no knowledge of the email they said they sent to customers tell them what they are going to do in their accounts, this November I'm expected to pay an amount of R2026.25 for things I have no knowledge about. I'm tired of all these Network companies charging us for things we know nothing about. People who use prepaid don't come across this problems and us the ones who have cellphone contract we are being ******. Where do they think I get the money for paying all this nonsense.

Please help me to help other who don't know what's happening to their accounts

Please find attached Page 18, a lot of R6.00 I can't explain Page19till 20, 0,50 that I don't know cause I didn't send sms with that number Page 21, R509.25 once off internet that I'm complaining that's don't know, and it's the one that they said they sent message to customers that they are going to do that.

And the ********** 680 SIM was destroyed by my 2year old daughter I don't use it cause I don't have it.
