Charges for stuff not used

I have asked numerous times about the BIS that's being charged but no one comes back to me. This has been going on since I have upgraded. The 1 contract was credited but not the other 1. I have asked them to send me a statement of the amount that was credited but they just don't care about you but they care about your money. I have change my banking detail as well and it was send through from my bank. End of November the debit order didn't go of. Now my service is suspended. Telkom is quick to suspend my service for the first time the debit didn't go of after I have send them my new banking details but very slow to respond if they are over charged me for things I do not use!!!! like the BIS. This was even requested at the Lake side branch to be removed and still it shows. <br> <br> Please I need an answer today as I've been struggling with this from the time I upgraded.<br>
