Incorrect billing for months

<p>Telkom has been charging me for Data that i have not been using . I called their callcentre twice and was told managment will contact me but no response . Ref number : ********** 70. </p> <p>I was over seas for 2 weeks the modem was turned off and i took a screen shot of the data used as Telkom has been charging me monthly but cannot provide the exact detail of the usuage . I was told they system ustomatically add a Fee of R500 to my bill which i have not signed for . I dont understand how it is possible for the modem to be turned off and for me to be over seas and when i receive the itemised bill iut shows data used which is impossible . The agents dont understand the products , They are not able to tell how much data was used . I have been told they will escalate its been a month and no response . I have asked for the R500 automatic fee to be cancelled i was told it was and i then receive my next bill with the R500 included . I need a reponse from Telkom as to how they can charge a person and provide a bill when the data was not used . That is seems abit fishy they are falsly charging customers </p>
