Telkom Bad Service (****************)

I have received my bill & there is R249 added on my bill so I am expected to pay R1 721.00 the following month. The sad part is that I don't know how this happened because I didn't add this on my cellphone bill. When I called customer care I spoke to lady name Nokwanda Ngcobo (agent). Agent was rude and when I asked about this money she asked me what must they do cause I already used the data in Zulu (SENZENJANI SENZENJANI) IN A HUSH TONE. I felt so little and disrespected. Agent failed to assist me with my query she didn't know what to do so, she kept telling me to wait than I had to listen to music the whole time. I then requested to speak to the supervisor when she came back on the line, she said the supervisor is listening to the call and they will get back at me. i told the agent i dont have time for that since I have been wait for almost 35 minute on the line. Agent then told me she will transfer me to the supervisor. As I am typing this the call is already 1h30 no one is coming through to assist. I have been waiting almost an hour no one is saying anything. If this is how telkom is treating their customers. i don't want to be part of this nonsense. These type of behavior in call center is ridiculous. I am am not even willing to pay for this if there is no proof of this transaction. I wont pay for something I didn't authorized as my monthly spending limit is R10 so how the hell did I end up being billed if I didn't increase my spending limit. Even on my statement there is no proof of this....... This is **************** and it is un acceptable
