Incorrect charges

<p>I signed a promotional contact with telkom for 5 gigs of data and 10 gigs night surfer for R149 pm. I specifically asked that if the data is depleted, I do not have internet access because I do not want to be charged any more than what I agreed to. This morning R590 was taken from my account for April spend. After speaking to the call center agent I was told that it will only be corrected from 1 July meaning that for May and June I will continue to be charged for something that I DID NOT ask for. I'm EXTREMELY dissatisfied. </p>
