Being charged for internet usage that is not mine.

<p>Writing here to get your attention Telkom. I wrote a few emails to ********** last month, because I was charged for usage when I was out of the country! I got a response that the fault was on your side. And that they would get back to me. They still have not, even though I emailed again, and then phoned and had a dispute logged for that July invoice. I had to pay the July invoice so long, which I did. Now my August invoice is even higher!!! Even though I topped up and paid for it by creditcard manually. This cannot be. Just sent another email to ********** and tried to phone. No response from your side... Rectify this, now please! Thank you, Karen</p>
